Whether the refusal to extend the judicial deadline was appealable because it caused irreparable harm
No; any alleged violation of the right to be heard could be raised later in an appeal against the lifting order, so no difficult-to-repair harm existed.
A refusal to extend time is an instruction order; an appeal lies only if it may cause difficult-to-repair prejudice. The appellant could still obtain effective redress in a later merits appeal, and the continuation of the proceedings did not create important costs.
