interim orders that cannot be contested separately by appeal;
rulings that are contestable by objection;
rulings in which the authority grants the application of the parties in full;
enforcement measures;
other rulings in proceedings of first instance if there is a risk in any delay, the parties have the right to appeal against the ruling and no other provision of federal law guarantees the right to preliminary hearing.
