There’s an argument in favour of setting a maximum term for Supreme Court Judges.

A report from New Zealand Initiative suggests the Supreme Court is getting an exaggerated view of its role and straying into Parliament's domain.

Former ACT MP and lawyer Stephen Franks says there's been grumblings about it among some lawyers.

He told Ryan Bridge that at the 20th anniversary of the Supreme Court this year, a leading KC presented a paper aligned with this belief.

He says it read that the law is ceasing to be predictable as the Supreme Court's changing it according to their social values.
