Can you help? basic info needed

Deadlines: There's no fixed amount of time, it depends on when the parties file their briefs, and the court has to make some decisions too. For Bilksi, I think we had the maximum, and it was four months. Certiorari was granted on 1 June and briefs were in by 1 October.

As a citizen or via a lawyer?

Ordinary citizens can submit amicus briefs, but the procedure is a little more complicated and the deadline falls a little bit earlier.

If the brief is submitted by a lawyer who is admitted to the bar of the court in question, the procedure is simpler.
