OTTAWA - The Supreme Court of Canada will deliver a one-of-a-kind pronouncement today on what it takes to serve on the high court.
It's decision that could trigger political shock waves.
The high court will release its long-awaited opinion about whether Prime Minister Harper's appointment of a semi-retired federal appeal court judge is allowed under the Supreme Court Act.
Harper's decision in September to nominate 64-year-old Marc Nadon to fill one of three Supreme Court seats reserved for Quebec has been challenged by a Toronto lawyer.
Rocco Galati argues that Nadon does not meet the qualifications to fill one of the mandatory Quebec vacancies because he came from the Federal Court and not a Quebec court.
Nadon has been strictly quarantined from the eight remaining justices and is staying away from country's highest courthouse.
The government asked the Supreme Court for an opinion on Nadon's eligibility.
If the Supreme Court sides with Galati, it would be a serious political rebuke to Harper.
