hm i don't think she can request the land the prison is on but there are things she could do like expose them(well she already did it but only to those watching the trial), get them fired or something, maybe she could ask to select who will be in charge of the prison... she can't really ask for their freedom since they committed crimes even if small ones and it would be offensive to the judiciary system who is already in a bad situation for arresting the wrong person
i believe she will probably ask for the crown to make it legal to give formal education to women and allow women to learn the empire official language (remember how her teacher was arrested for teaching it to women?)
