I.  Introduction

A New Zealand case involving an application for refugee status based on the effects of climate change in the Pacific Island nation of Kiribati has received media attention around the world.  The proceedings in the case came to a close in July 2015, when the Supreme Court of New Zealand, the highest court in the country, dismissed an application for leave to appeal the Court of Appeal’s decision in which it ruled against the applicant.

This report summarizes the decisions of the different courts that issued rulings in the case and provides information on other Australian and New Zealand cases that involved refugee claims based on the impacts of climate change in different countries.  Links to media articles and academic writings that include discussion of the New Zealand case are provided at the end of this report.

II.  Case Summary

Mr. Ioane Teitiota and his wife moved to New Zealand from Kiribati in 2007.  They subsequently had three children, who were born in New Zealand but not entitled to New Zealand citizenship under the Citizenship Act 1977.  The family remained in the country illegally following the expiration of their visas in October 2010.  To avoid deportation, Mr. Teitiota applied for refugee status under Part 5 of the Immigration Act 2009.  This legislation incorporates into domestic law the 1951 Convention Relating to the Status of Refugees.

Mr. Teitiota claimed that he was entitled to be recognized as a refugee “on the basis of changes to his environment in Kiribati caused by sea-level-rise associated with climate change.”[1]  A refugee and protection officer declined to grant refugee status, and this decision was upheld by the Immigration and Protection Tribunal.  Mr. Teitiota subsequently sought leave from the High Court to appeal the Tribunal’s decision on questions of law under section 245 of the Immigration Act 2009.  His application for leave to appeal to the High Court was declined by both the High Court and Court of Appeal in 2013 and 2014, respectively.  On July 20, 2015, the Supreme Court upheld the decisions of the lower courts and dismissed Mr. Teitiota’s application for leave to appeal.

III.  Court Decisions

A.  Immigration and Protection Tribunal

The Immigration and Protection Tribunal (IPT) is an independent body that hears appeals from decisions made by Immigration New Zealand, including those of refugee and protection officers within the Refugee Status Branch.  Immigration New Zealand is part of the Ministry of Business, Innovation and Employment (MBIE).

The IPT dismissed Mr. Teitiota’s appeal in a decision issued in June 2013.  It noted that “the limited capacity of South Tarawa to carry its population is being significantly compromised by the effects of population growth, urbanisation, and limited infrastructure development, particularly in relation to sanitation.  The negative impacts of these factors on the carrying capacity of the land on Tarawa atoll are being exacerbated by the effects of both sudden onset environmental events (storms) and slow-onset processes (sea-level-rise).”[2] However, the IPT considered that the appellant “has undertaken what may be termed a voluntary adaptive migration,” and that his decision to migrate to New Zealand could not be seen as “forced.”[3]

In examining the concept of persecution under New Zealand and international refugee law, the IPT stated that it involves either failure of the state to control its own agents who commit human rights violations, or failure to take steps to reduce the risk of harm being perpetrated by non-state actors.[4]  However, it did note that “this requirement of some form of human agency does not mean that environmental degradation, whether associated with climate change or not, can never create pathways into the Refugee Convention or protected person jurisdiction.”[5]

The IPT went on to consider international law with respect to natural disasters and environmental degradation, stating that while these can involve significant human rights issues, the claimant must still establish that they meet the legal criteria set out in the Refugee Convention.  In the New Zealand context, this means showing “a real chance of a sustained or systemic  violation  of  a  core  human  right  demonstrative  of  a  failure  of  state protection which has sufficient nexus to a Convention ground.”[6]

The IPT found that the evidence did not show that the environmental conditions faced, or likely faced, by the appellant should he return to Kiribati “are so parlous that his life will be placed in jeopardy, or that he and his family will not be able to resume their prior subsistence life with dignity.”[7]  In any event, it considered that the effects of environmental degradation on his standard of living were being faced by the population generally, and it had not been suggested that the Kiribati government has failed to take adequate steps to protect the appellant from harm.[8]   Therefore, the IPT found that the appellant was not a refugee within the meaning of the Refugee Convention.[9]

B.  High Court

Mr. Teitiota applied to the High Court for leave to appeal the IPT’s decision on points of law.  In refusing to grant leave to appeal, the High Court called the appellant’s arguments “novel and optimistic” but found them “unconvincing.”[10]  In essence, the judge agreed with the IPT’s findings and stated that it was not for the Court to alter the scope of the Refugee Convention so as to entitle people facing medium-term economic deprivation or the immediate consequences of natural disasters or warfare to protection.[11]  He stated that “a ‘sociological’ refugee or person seeking to better his or her life by escaping the perceived results of climate change is not a person to whom Article 1A(2) of the Refugee Convention applies.”[12] 

C.  Court of Appeal

Mr. Teitiota sought to overturn the High Court’s decision by applying to the Court of Appeal.  The Court of Appeal also held that the IPT’s reasoning had not been erroneous in law and declined to grant leave to appeal, stating that

the Tribunal essentially applied well developed law, which it correctly understood, to the undisputed facts of Mr Teitiota’s case.  The short point is that the effects of climate change on Mr Teitiota, and indeed on the population of Kiribati generally, do not bring him within the Convention.  That is the position even if the most sympathetic, ambulatory approach permissible to interpreting the Convention is taken.  The Convention is quite simply not the solution to Kiribati’s problem.[13]

The Court further stated that, although it has “every sympathy with the people of Kiribati, Mr. Teitiota’s claim for recognition as a refugee is fundamentally misconceived. It attempts to stand the Convention on its head.”[14]

D.  Supreme Court

Mr. Teitiota subsequently applied to the Supreme Court for leave to appeal against the decision of the Court of Appeal.  According to news reports, on June 10, 2015, the Supreme Court ruled that it had jurisdiction to consider the application and ordered the appellant to file and serve submissions by June 26, 2015, and that the MBIE file and serve its submissions by July 3, 2015.[15]

The Supreme Court’s decision was subsequently issued on July 20, 2015.[16]  In agreeing with the courts below, the five-member panel held that “in the particular factual context of this case (even with the addition of the new evidence), the questions identified raise no arguable question of law of general or public importance.”[17]  The new evidence referred to was the November 2014 Synthesis Report of the Fifth Assessment Report of the Intergovernmental Panel on Climate Change, as well as the original MBIE decision.  It confirmed the lower courts’ findings that, in relation to the Refugee Convention, Mr. Teitiota does not face “serious harm” and further that “there is no evidence that the Government of Kiribati is failing to take steps to protect its citizens from the effects of environmental degradation to the extent that it can.”[18]

The Supreme Court did note, however, the statements of the IPT and High Court that their decisions “did not mean that environmental degradation resulting from climate change or other natural disasters could never create a pathway into the Refugee Convention or protected person jurisdiction.”[19]  The Court similarly explicitly stated that its decision in this particular case “should not be taken as ruling out that possibility in an appropriate case.”[20]

IV.  Other Refugee Cases Involving Climate Change

The decision of the IPT in the Teitiota case notes that there were a number of cases in 2000 that involved claimants from Tuvalu seeking recognition as refugees in New Zealand due to various environmental factors, including “inundation, coastal erosion, salination of the water table, combined with factors at the individual and household levels.”[21]  The IPT lists the following seven such cases, in which all of the claims were dismissed by the New Zealand Refugee Status Appeals Authority, the predecessor of the IPT, “because the indiscriminate nature of these events and processes gave rise to no nexus to a [Refugee] Convention ground”:[22]

In the High Court, Mr. Teitiota’s lawyer “candidly submitted” that he had been unable to find “any New Zealand, Australian, Canadian, United Kingdom, United States, or European authority which had extended the protection of the Refugee Convention to a person adversely affected by climate change.”[23]  The High Court judge noted that “[t]o the contrary, there are many decisions rejecting claims by people from Kiribati, Tuvalu, Tonga, Bangladesh, and Fiji on the grounds that the harm feared (environmental problems in low-lying countries attributable to climate change) does not amount to persecution and there were no differential impacts on the applicants.”[24]  Among the cases he cited were the following:[25]

In the Australian Refugee Review Tribunal Decision in 0907346 [2009] RRTA 1168, the Tribunal affirmed the decision to decline a refugee visa to an applicant from Kiribati, finding that “[t]here appears no doubt that the circumstances the applicant, and others living in Kiribati, face are serious and deserving of significant Governmental consideration and attention. They are not matters against which, however, the Refugees Convention as it applies in Australia is able to provide protection.”[26]

In a 2010 paper on climate change displacement, in addition to some of the cases referred to above, an Australian expert on refugee law cited the following Australian refugee or protection visa cases, decided by the Refugee Review Tribunal of Australia, that refer to the impacts of climate change in Tuvalu:[27]

More recently, in 2014, the IPT similarly dismissed an appeal from a Tuvalu family that had sought refugee status in New Zealand on the basis of the effects of climate change in their home country.[28]  However, in a separate decision, the IPT allowed the family to remain in New Zealand due to “exceptional circumstances of a humanitarian nature, which would make it unjust or unduly harsh for the appellants to be removed from New Zealand.”[29]  The relevant circumstances involved close family ties within the country that would be severely disrupted by removal.  This case received some media coverage outside of New Zealand and is discussed in an article by the same Australian legal expert referred to above.[30]
