Courts around the world are increasingly being asked to determine whether governments and Crown corporations are doing enough to address climate change.

Key Points: 
  • Courts around the world are increasingly being asked to determine whether governments and Crown corporations are doing enough to address climate change.
  • In the past few weeks, courts in Belgium and Germany have ordered greater emissions reductions from national governments.
  • It accepts that courts are an appropriate way to resolve the hotly contested issues at the centre of climate policy.

‘Justiciability 101’

  • Justiciability marks the line between what should be decided by courts versus other government branches.
  • In 2012, the same court decided that the federal government’s decision to leave the Kyoto Protocol was also not a matter for the courts.

A turning tide?

  • The first was a youth-led challenge to current federal climate policy based on its disproportionate harms to young people.
  • The second one involved two Wet’suwet’en House groups claiming that federal climate policy violated their rights under the Canadian Charter of Rights and Freedoms.
  • According to the lower court, these challenges were “too political” for courts to resolve and better left to legislators and government officials.
  • The lower court rulings put an early end to both challenges, preventing judicial scrutiny of claims of rights violations.

Perverse incentives?

  • Governments expose themselves to court challenges when they enact laws and regulations, but not when they merely make policy statements.
  • This approach fails to capture how government inaction can itself be a political decision affecting constitutional and other rights.
  • The Federal Court of Appeal’s broader understanding of what constitutes a legal anchor may also alleviate this issue.

The future role of courts

  • Going forward, the increase in cases related to climate change and climate policy will test the balance between courts and other government branches.
  • Now those most suffering the effects of climate change want and need courts to act on climate when governments fail to do so.
