Ahmedabad air crash

Whenever a serious aviation incident or accident occurs anywhere in the world, attention is focused on the regulatory authority of the country of registration of the aircraft. The incident/accident investigation itself is conducted by the country (state) of occurrence, with the involvement of the manufacturers of the aircraft and engines, under the guidance of regulatory authorities such as the National Transportation Safety Board, USA (NTSB), Federal Aviation Administration (FAA), European Aviation Safety Agency (EASA) and International Civil Aviation Organisation (ICAO) as necessary.

Regarding the Air India accident of June 12, 2025, the spotlight is now on the Civil Aviation Department (CAD) and AAIB (Aircraft Accident Investigation Bureau) of India. While the CAD is a government department, the AAIB is nominally at least an independent authority. Unfortunately, in India as in Sri Lanka, true independence of accident investigation has not been achieved.

Although established much later than Air India International, airlines such as Air Ceylon, Air Lanka and SriLankan Airlines are regulated by government entities with conflicts of interest. Beginning in December 1947, with the inauguration of Air Ceylon, the new national carrier was in fact operated by the Civil Aviation Department. Only in March 1951 did Air Ceylon become a Corporation (Air Ceylon Ltd). Even then, the Director of Civil Aviation remained a member of the Air Ceylon Board, entitled to the perquisites of the airline such as free tickets.

Currently, Sri Lankan Airlines operates to many overseas destinations, with the potential of becoming involved in high-profile incidents and accidents. If the spotlight is turned on Sri Lanka, the world will discover that Sri Lanka’s Civil Aviation Act number 14 is dated 2010, and the Air Navigation Regulations (ANR) are dated 1955! This disparity is totally inappropriate for our aviation industry as aviation is a very dynamic, high- tech industry. Like in India Sri Lanka too does not have an Independent Air Accident Investigation Branch.

 The Civil Aviation Authority of Sri Lanka (CAASL) was inaugurated on December 27, 2002, with much fanfare, in accordance with the Civil Aviation Authority Sri Lanka Act no. 34, with Mr Upali Malalgoda appointed as Director General of Civil Aviation.

Unfortunately, after the formation of the CAASL the objectives given below, with their ‘powers, functions and duties’ have not been effectively observed and fulfilled over the past 23 years. I shall attempt to discuss each objective while expressing my own views, comments and queries.

(a)  Subject to any directions issued by the Minister (of Aviation), regulate civil air operations within the territory of Sri Lanka and the operation of Sri Lanka registered aircraft outside the territory of Sri Lanka in accordance with the provision of the act or any other written law.

 Firstly, is the present minister or his deputy qualified to give directions to the CAASL on how to carry out its duties and functions? While international guidelines are available in writing in the 19 Annexes to International Civil Aviation Organization (ICAO) Chicago Convention of 1944, with regard to guidelines within the territory of Sri Lanka (domestic aviation), it is the CAASL who should advise the Minister and his team on the priorities. Presently, the Minister of Civil Aviation may not receive the right advice and be easily misled. CAASL staff have been occupying the same positions for decade, secure in their ‘comfort zones’, but are widely deemed to be unable to ‘think out of the box’.

  (b) To assist the Minister in the formation of the National Aviation Policy of Sri Lanka

The National Aviation Policy was written in consultation with the stakeholders and passed by Parliament in 2017, but has failed to be implemented by the CAASL. Sadly, apart from the policy having been forgotten, ignored or deliberately sidelined, some members of the CAASL staff do not even know that such a national policy even exists.

 (c)  Prepare an Aviation Development Plan for Sri Lanka in accordance with the Aviation Policy and the directions issued by the Minister in regard to the same. 

No such plan exists.

(d) Provide strategic direction for the development of civil aviation and coordinate the activities of all parties involved.

 No such document exists.

 (e) Develop and promulgate or adopt by reference as appropriate clear and concise aviation safety requirements and practices and procedures. Implement effective enforcement strategies to secure compliance by all persons of the standards and such aviation safety requirements and practices and procedures.

Predictive, preventive and proactive aviation safety practices do not exist in the CAASL. Their actions are mainly reactive. There is no proper safety/risk assessment and management. The most convenient way is to stop operations and not attempt to identify and manage the risks. Importantly and more seriously, there are no officers with knowledge and hands-on aviation experience. For example, para-motors have all been grounded, imposing hardship on operators.

(f)   Encourage through comprehensive and timely aviation safety advice and by fostering an awareness within the aviation community of the importance of aviation safety. A greater degree of acceptance by the aviation community of its obligation to maintain a high standard of aviation safety, provide aviation safety education and training for persons involved in civil aviation activities.

 The aviation community is not consulted in these matters. Programmess such as these are few and far between as there are no airline pilots, retired or active, save one working in CAASL. Most posts are filled by former non-pilot air traffic control officers. This situation is not acceptable.

 (g)  Issue certificates, licences, permits and any other legal authority or documentation issued by or under the provisions of this act or any other written law.

Many stakeholders have observed that the CAASL does not play the role of facilitator. It takes an unacceptably long time to get the necessary permission for any new operation, unlike in, say, the Maldives. CAASL’s actions are lackadaisical at best, and inconsistent. They don’t deal with an even hand. There have also been allegations of bribery and corruption, which is dangerous in aviation.

 (h) Initiate investigations on aircraft accidents and other related incidents and arrange for the establishment and provision of search and rescue operations; conduct inquiries with regard to any flight safety hazard and take remedial action. 

 With accidents happening closer to home, such as AI 171 in Ahmedabad, CAASL has suddenly woken up to the fact that there is no qualified effective independent air accident investigation authority to handle incidents and accidents in Sri Lanka. The laws in Sri Lanka are still not in place.

 Who should be the members of the CAASL in accordance with CAASL Act number 34?

1. (a) the Secretary to the Ministry of the Minister in charge of the subject of Defence;

(b) a representative of the Ministry of the Minister in charge of the subject of Finance, nominated by that Minister;

(c) five persons appointed by the Minister of whom not less than two shall have considerable experience or knowledge in the field of civil aviation : and

(d) The Director-General.

 With reference to 1b, there is no-one qualified in civil aviation in the present CAASL Board, let alone two. There is a SLAF helicopter pilot who is not qualified in civil aviation. This sad situation cannot get worse. As a result the system is about to collapse. Yet the government seems to be totally unaware or unconcerned.

2. The Minister shall appoint one of the members of the Authority, to be its Chairman and one other member to be its Vice-Chairman

 3. The Minister shall in appointing a member under paragraph (c) of subsection (1), satisfy himself that such member has no financial or other interest in any airline or aviation related business that is likely to prejudicially affect the discharge of his or her functions as such member, and further shall also satisfy himself from time to time that such member has no such interest.

 4 The Chairman may by written authority, authorise any member of the Authority to perform any of the functions conferred upon him as Chairman.

 5 The provisions of the First Schedule to this Act, shall apply to and in relation to the members of the Authority, its meetings and the seal of the Authority.

 The present CAASL Board is listed as below

 Chairman: Sunil Jayaratne

Acting Director General/CEO: Rayhan Wanniappa, Attorney at Law

Member: K.G. Kumarasinghe

Member: Shameera Priyankarage

Member (Ex Officio, Defence): AVM Sampath Thuyacontha, retired SLAF pilot

Member (Ex Officio, Treasurer): Pradeep Kumara

 From the above it can be seen that the Government of Sri Lanka has not heeded the requirements of CAASL Act no. 34. None of the members of the CAASL have knowledge or experience in civil aviation. Would the government or CAASL care to comment?

 Accidents don’t happen only to others. If our civil aviation system is found deficient at scrutiny by ICAO and other international organisations, SriLankan Airlines can be banned from overflying other countries. It has happened to many airlines, including Bangladesh and Pakistan International Airlines in the UK.

See the Tables 1 and 2 for a full list of banned airlines in the European Union and the US

 Banned air carriers could be permitted to exercise traffic rights by using wet-leased aircraft of an air carrier which is not subject to an operating ban, provided that the relevant safety standards are complied with. The list includes the following airlines, with the airline licence having been issued in the respective countries.

 FAA Banned Countries from The Internet

The FAA maintains a list of countries whose airlines are banned from operating in the United States because they do not meet minimum standards for aviation safety and do not maintain sufficient oversight of carriers within their own borders. Below are countries whose airlines are banned by the FAA from operating in the United States.

* Bangladesh

* Barbados

* Belize

* Cote D’ Ivoire

* Curacao

* Democratic Republic of Congo (formerly Zaire)

* Gambia

* Ghana

* Haiti

* Honduras

* Indonesia

* Kiribate*

* Montenegro

* Nauru

* Nicaragua

* Paraguay

* Philippines

* Serbia

* Saint Maarten

 Are we in Sri Lanka sitting on a time bomb here?

Retirement age for judges: Innovation and policy

Published

on

I. The Constitutional Context

Independence of the judiciary is, without question, an essential element of a functioning democracy. In recognition of this, ample provision is made in the highest law of our country, the Constitution, to engender an environment in which the courts are able to fulfil their public responsibility with total acceptance.

As part of this protective apparatus, judges of the Supreme Court and the Court of Appeal are assured of security of tenure by the provision that “they shall not be removed except by an order of the President made after an address of Parliament supported by a majority of the total number of members of Parliament, (including those not present), has been presented to the President for such removal on the ground of proved misbehaviour or incapacity”[Article 107(2)]. Since this assurance holds good for the entirety of tenure, it follows that the age of retirement should be defined with certainty. This is done by the Constitution itself by the provision that “the age of retirement of judges of the Supreme Court shall be 65 years and of judges of the Court of Appeal shall be 63 years”[Article 107(5)].

II. A Proposal for Reform

This provision has been in force ever since the commencement of the Constitution. Significant public interest, therefore, has been aroused by the lead story in a newspaper, Anidda of 13 March, that the government is proposing to extend the term of office of judges of the Supreme Court and the Court of Appeal by a period of two years.

This proposal, if indeed it reflects the thinking of the government, is deeply disturbing from the standpoint of policy, and gives rise to grave consequences. The courts operating at the apex of the judicial structure are called upon to do justice between citizens and also between the state and members of the public. It is an indispensable principle governing the administration of justice that not the slightest shadow of doubt should arise in the public mind regarding the absolute objectivity and impartiality with which the courts approach this task.

What is proposed, if the newspaper report is authentic, is to confer on judges of two particular courts, the Supreme Court and the Court of Appeal, a substantial benefit or advantage in the form of extension of their years of service. The question is whether the implications of this initiative are healthy for the administration of justice.

III. Governing Considerations of Policy

What is at stake is a principle intuitively identified as a pillar of justice.

Reflecting firm convictions, the legal antecedents reiterate the established position with remarkable emphasis. The classical exposition of the seminal standard is, of course, the pronouncement by Lord Hewart: “It is not merely of some importance, but is of fundamental importance that justice should not only be done, but should manifestly and undoubtedly be seen to be done”. (Rex v. Sussex Justices, ex parte McCarthy). The underlying principle is that perception is no less important than reality. The mere appearance of partiality has been held to vitiate proceedings: Dissanayake v. Kaleel. In particular, reasonableness of apprehension in the mind of the parties to litigation is critical: Ranjit Thakur v. Union of India, a reasonable likelihood of bias being necessarily fatal (Manak Lal v. Prem Chaud Singhvi).

The overriding factor is unshaken public confidence in the judiciary: State of West Bengal v. Shivananda Pathak. The decision must be “demonstrably” (Saleem Marsoof J.) fair. The Bar Association of Sri Lanka has rightly declared: “The authority of the judiciary ultimately depends on the trust reposed in it by the people, which is sustained only when justice is administered in a visibly fair manner”.

Credibility is paramount in this regard. “Justice has to be seen to be believed” (J.B. Morton). Legality of the outcome is not decisive; process is of equal consequence. Judicial decisions, then, must withstand public scrutiny, not merely legal technicality: Mark Fernando J. in the Jana Ghosha case. Conceived as continuing vitality of natural justice principles, these are integral to justice itself: Samarawickrema J. in Fernando v. Attorney General. Institutional integrity depends on eliminating even the appearance of partiality (Mandal Vikas Nigam Ltd. v. Girja Shankar Pant), and “open justice is the cornerstone of our judicial system”: (Sahara India Real Estate Corporation Ltd. v. SEBI).

IV. Practical Constraints

Apart from these compelling considerations of policy, there are practical aspects which call for serious consideration. The effect of the proposal is that, among all judges operating at different levels in the judicature of Sri Lanka, judges of the Supreme Court and the Court of Appeal only, to the exclusion of all other judges, are singled out as the beneficiaries of the proposal. An inevitable result is that High Court and District Judges and Magistrates will find their avenues of promotion seriously impeded by the unexpected lengthening of the periods of service of currently serving judges in the two apex courts. Consequently, they will be required to retire at a point of time appreciably earlier than they had anticipated to relinquish judicial office because the prospect of promotion to higher courts, entailing higher age limits for retirement, is precipitately withdrawn. Some degree of demotivation, arising from denial of legitimate expectation, is therefore to be expected.

A possible response to this obvious problem is a decision to make the two-year extension applicable to all judicial officers, rather than confining it to judges of the two highest courts. This would solve the problem of disillusionment at lower levels of the judiciary, but other issues, clearly serious in their impact, will naturally arise.

Public service structures, to be equitable and effective, must be founded on principles of non-discrimination in respect of service conditions and related matters. Arbitrary or invidious treatment is destructive of this purpose. In determining the age of retirement of judges of the Supreme Court and the Court of Appeal, some attention has been properly paid to balance and consistency. The age of retirement of a Supreme Court judge is on par with that applicable to university professors and academic staff in the higher education system. They all retire at 65 years. Members of the public service, generally, retire at 60. Medical specialists retire at 63, with the possibility of extension in special circumstances to 65. The age of retirement for High Court Judges is 61, and for Magistrates and District Judges 60. It may be noted that the policy change in 2022 aimed at specifically addressing the issue of uniformity and compatibility.

If, then, an attempt is made to carve out an ad hoc principle strictly limited to judicial officers, not admitting of a self-evident rationale, the question would inevitably arise whether this is fair by other categories of the public service and whether the latter would not entertain a justifiable sense of grievance.

This is not merely a moral or ethical issue relating to motivation and fulfillment within the public service, but it could potentially give rise to critical legal issues. It is certainly arguable that the proposed course of action represents an infringement of the postulate of equality of treatment, and non-discrimination, enshrined in Article 12(1) of the Constitution.

There would, as well, be the awkward situation that this issue, almost certain to be raised, would then have to be adjudicated upon by the Supreme Court, itself the direct and exclusive beneficiary of the impugned measure.

V. Piecemeal Amendment or an Overall Approach?

If innovation on these lines is contemplated, would it not be desirable to take up the issue as part of the new Constitution, which the government has pledged to formulate and enact, rather than as a piecemeal amendment at this moment to the existing Constitution? After all, Chapter XV, dealing with the Judiciary, contains provisions interlinked with other salient features of the Constitution, and an integrated approach would seem preferable.

VI. Conclusion

In sum, then, it is submitted that the proposed change is injurious to the institutional integrity of the judiciary and to the prestige and stature of judges, and that it should not be implemented without full consideration of all the issues involved.

Ranked 134th in Happiness: Rethinking Sri Lanka’s development through happiness, youth wellbeing and resilience

Published

on

In recent years, Sri Lanka has experienced a succession of overlapping challenges that have tested its resilience. Cyclone Ditwah struck Sri Lanka in November last year, significantly disrupting the normal lives of its citizens. The infrastructure damage is much more serious than the tsunami. According to World Bank reports and preliminary estimates, the losses amounted to approximately US$ 4.1 billion, nearly 4 per cent of the country’s Gross Domestic Product. Before taking a break from that, the emerging crisis in the Middle East has once again raised concerns about potential economic repercussions. In particular, those already affected by disasters such as Cyclone Ditwah risk falling “from the frying pan into the fire,” facing multiple hardships simultaneously. Currently, we see fuel prices rising, four-day workweeks, a higher cost of living, increased pressure on household incomes, and a reduction in the overall standard of living for ordinary citizens. It would certainly affect people’s happiness. As human beings, we naturally aspire to live happy and fulfilling lives. At a time when the world is increasingly talking about happiness and wellbeing, the World Happiness Report provides a useful way of looking at how countries are doing. The World Happiness Report discusses global well-being and offers strategies to improve it. The report is produced annually with contributions from the University of Oxford’s Wellbeing Research Centre, Gallup, the UN Sustainable Development Solutions Network, and other stakeholders. There are many variables taken into consideration for the index, including the core measure (Cantril Ladder) and six explanatory variables (GDP per Capita ,Social Support,Healthy Life Expectancy,Freedom to Make Life Choices,Generosity,Perceptions of Corruption), with a final comparison.

According to the recently published World Happiness Report 2026, Sri Lanka ranks 134th out of 147 nations. As per the report, this is the first time that Sri Lanka has suffered such a decline. Sri Lanka currently trails behind most of its South Asian neighbours in the happiness index. The World Happiness Report 2026 attributes Sri Lanka’s low ranking (134th) to a combination of persistent economic struggles, social challenges, and modern pressures on younger generations. The 2026 report specifically noted that excessive social media use is a growing factor contributing to declining life satisfaction among young people globally, including in Sri Lanka. This calls for greater vigilance and careful reflection. These concerns should be examined alongside key observations, particularly in the context of education reforms in Sri Lanka, which must look beyond their immediate scope and engage more meaningfully with the country’s future.

In recent years, a series of events has triggered political upheaval in countries such as Nepal, characterised by widespread protests, government collapse, and the emergence of interim administration. Most reports and news outlets described this as “Gen Z protests.” First, we need to understand what Generation Z is and its key attributes. Born between 1997 and 2012, Generation Z represents the first truly “digital native” generation—raised not just with the internet, but immersed in it. Their lives revolve around digital ecosystems: TikTok sets cultural trends, Instagram fuels discovery, YouTube delivers learning, and WhatsApp sustains peer communities. This constant, feed-driven engagement shapes not only how they consume content but how they think, act, and spend. Tech-savvy and socially aware, Gen Z holds brands to a higher standard. For them, authenticity, transparency, and accountability—especially on environmental and ethical issues—aren’t marketing tools; they’re baseline expectations. We can also observe instances of them becoming unnecessarily arrogant in making quick decisions and becoming tools of some harmful anti-social ideological groups. However, we must understand that any generation should have proper education about certain aspects of the normal world, such as respecting others, listening to others, and living well. More interestingly, a global survey by the McKinsey Health Institute, covering 42,083 people across 26 countries, finds that Gen Z reports poorer mental health than older cohorts and is more likely to perceive social media as harmful.

Youth health behaviour in Sri Lanka reveals growing concerns in mental health and wellbeing. Around 18% of youth (here, school-going adolescents aged 13-17) experience depression, 22.4% feel lonely, and 11.9% struggle with sleep due to worry, with issues rising alongside digital exposure. Suicide-related risks are significant, with notable proportions reporting thoughts, plans, and attempts, particularly among females. Bullying remains a significant concern, particularly among males, with cyberbullying emerging as a notable issue. At the same time, substance use is increasing, including tobacco, smokeless tobacco, and e-cigarettes. These trends highlight the urgent need for targeted interventions to support youth mental health, resilience, and healthier behavioural outcomes in Sri Lanka. We need to create a forum in Sri Lanka to keep young people informed about this. Sri Lanka can designate a date (like April 25th) as a National Youth Empowerment Day to strengthen youth mental health and suicide prevention efforts. This should be supported by a comprehensive, multi-sectoral strategy aligned with basic global guidelines. Key priorities include school-based emotional learning, counselling services, and mental health training for teachers and parents. Strengthening data systems, reducing access to harmful means, and promoting responsible media reporting are essential. Empowering families and communities through awareness and digital tools will ensure this day becomes a meaningful national call to action.

As discussed earlier, Sri Lanka must carefully understand and respond to the challenges arising from its ongoing changes. Sri Lanka should establish an immediate task force comprising responsible stakeholders to engage in discussions on ongoing concerns. Recognising that it is not a comprehensive solution, the World Happiness Index can nevertheless act as an important indicator in guiding a paradigm shift in how we approach education and economic development. For a country seeking to reposition itself globally, Sri Lanka must adopt stronger, more effective strategies across multiple sectors. Building a resilient and prosperous future requires sound policymaking and clear strategic direction.

Hidden diversity in Sri Lanka’s killifish revealed: New study reshapes understanding of island’s freshwater biodiversity

Published

on

Aplocheilus parvus

A groundbreaking new study led by an international team of scientists, including Sri Lankan researcher Tharindu Ranasinghe, has uncovered striking genetic distinctions in two closely related killifish species—reshaping long-standing assumptions about freshwater biodiversity shared between Sri Lanka and India.

Published recently in Zootaxa, the research brings together leading ichthyologists such as Hiranya Sudasinghe, Madhava Meegaskumbura, Neelesh Dahanukar and Rajeev Raghavan, alongside other regional experts, highlighting a growing South Asian collaboration in biodiversity science.

For decades, scientists debated whether Aplocheilus blockii and Aplocheilus parvus were in fact the same species. But the new genetic analysis confirms they are “distinct, reciprocally monophyletic sister species,” providing long-awaited clarity to their taxonomic identity.

Speaking to The Island, Ranasinghe said the findings underscore the hidden complexity of Sri Lanka’s freshwater ecosystems.

“What appears superficially similar can be genetically very different,” he noted. “Our study shows that even widespread, common-looking species can hold deep evolutionary histories that we are only now beginning to understand.”

A tale of two fishes

The study reveals that Aplocheilus blockii is restricted to peninsular India, while Aplocheilus parvus occurs both in southern India and across Sri Lanka’s lowland wetlands.

Despite their close relationship, the two species show clear genetic separation, with a measurable “genetic gap” distinguishing them. Subtle physical differences—such as the pattern of iridescent scales—also help scientists tell them apart.

Co-author Sudasinghe, who has led several landmark studies on Sri Lankan freshwater fishes, noted that such integrative approaches combining genetics and morphology are redefining taxonomy in the region.

Echoes of ancient land bridges

The findings also shed light on the ancient biogeographic links between Sri Lanka and India.

Scientists believe that during periods of low sea levels in the past, the two landmasses were connected by the now-submerged Palk Isthmus, allowing freshwater species to move between them.

Later, rising seas severed this connection, isolating populations and driving genetic divergence.

“These fishes likely dispersed between India and Sri Lanka when the land bridge existed,” Ranasinghe said. “Subsequent isolation has resulted in the patterns of genetic structure we see today.”

Meegaskumbura emphasised that such patterns are increasingly being observed across multiple freshwater fish groups in Sri Lanka, pointing to a shared evolutionary history shaped by geography and climate.

A deeper genetic divide

One of the study’s most striking findings is that Sri Lankan populations of A. parvus are genetically distinct from those in India, with no shared haplotypes between the two regions.

Dahanukar explained that this level of differentiation, despite relatively recent geological separation, highlights how quickly freshwater species can diverge when isolated.

Meanwhile, Raghavan pointed out that these findings reinforce the importance of conserving habitats across both countries, as each region harbours unique genetic diversity.

Implications for conservation

The study carries important implications for conservation, particularly in a country like Sri Lanka where freshwater ecosystems are under increasing pressure from development, pollution, and climate change.

Ranasinghe stressed that understanding genetic diversity is key to protecting species effectively.

“If we treat all populations as identical, we risk losing unique genetic lineages,” he warned. “Conservation planning must recognise these hidden differences.”

Sri Lanka is already recognised as a global biodiversity hotspot, but studies like this suggest that its biological richness may be even greater than previously thought.

A broader scientific shift

The research also contributes to a growing body of work by scientists such as Sudasinghe and Meegaskumbura, challenging traditional assumptions about species distributions in the region.

Earlier studies often assumed that many freshwater fish species were shared uniformly between India and Sri Lanka. However, modern genetic tools are revealing a far more complex picture—one shaped by ancient geography, climatic shifts, and evolutionary processes.

“We are moving from a simplistic view of biodiversity to a much more nuanced understanding,” Ranasinghe said. “And Sri Lanka is proving to be a fascinating natural laboratory for this kind of research.”

Looking ahead

The researchers emphasise that much remains to be explored, with several freshwater fish groups in Sri Lanka still poorly understood at the genetic level.

For Sri Lanka, the message is clear: beneath its rivers, tanks, and wetlands lies a largely untapped reservoir of evolutionary history.

As Ranasinghe puts it:

“Every stream could hold a story of millions of years in the making. We are only just beginning to read them.”
