UBC law professor analysis finds the Supreme Court is more divided than in past years

OTTAWA, Jan. 15, 2016 – Some striking new trends emerged from the Supreme Court’s major decisions in 2015, a new report from the Macdonald-Laurier Institute finds.

The report, authored by UBC law professor and MLI Senior Fellow Benjamin Perrin, reveals several key findings:

  1. The former federal Conservative government’s losing record on major cases at the Court continued in 2015;
  2. The Court has overturned its own precedents in a growing number of major Charter decisions; and
  3. The consensus within the Court on major decisions has not been maintained, and there are strong voices within the court itself raising the alarm that it must not intrude into Parliament’s public policy domain.

Ben PerrinPerrin’s analysis examines the 10 most important cases the Court ruled on between Nov. 1, 2014 and Oct. 31, 2015. This includes several particularly significant cases, including decisions on: physician-assisted suicide, collective bargaining, freedom of religion, mandatory minimum sentences and damages for Charter violations.

The 2015 report is designed as a follow-up to Perrin’s 2014 MLI study, which examined the 10 most important cases of 2014.

Another losing record

In 2015, Perrin found, the former federal Conservative government won in only two of the eight cases in which it participated.

This losing record is substantially worse than historical trends for Charter litigation before the Court; on average, various levels of government have historically succeeded in 59 per cent of Charter cases.

"It appears that the ability of Charter claimants to re-litigate decided constitutional cases has expanded in recent years”

It is, however, a continuation of the trend from 2014. That year, the Conservatives won only one of 10 major cases.

Included among the losses in 2015 were some major political and policy defeats. The Court helped derail the government’s agenda on mandatory minimum sentences, physician-assisted suicide, medical marijuana derivatives and labour rights.

Overturning precedents

An emerging trend is the Court’s willingness to overturn precedent established in previous decisions.

SCC2015reportcover“While the Court professes to not lightly overturn its own precedents, it appears that the ability of Charter claimants to re-litigate decided constitutional cases has expanded in recent years”, Perrin writes.

This has led, Perrin finds, to some judges expressing discomfort about the Court’s willingness to turn its back on recent precedents.

A divided Supreme Court

Finally, the Court has never been so divided. Perrin finds that five out of the 10 cases examined involved judges writing dissenting opinions.

“What is even more interesting than the quantitative aspect of the rise of dissenting decisions on major cases in this year’s report is that they included at times blistered criticism of majority judges for allegedly intruding on Parliament’s policy-making domain”, writes Perrin.

This disunity was a departure from 2014, when there were dissenting opinions in only two of the 10 cases examined.
