From Google: An injunction is an equitable remedy in the form of a court order that either prohibits or compels ("enjoins" or "restrains") a party from continuing a particular activity. The party that fails to adhere to the injunction faces civil or criminal contempt of court and may have to pay damages or sanctions for failing to follow the court's order.
Basiclly, for example, if ACLU were to win a case involving 'a cross on public property,' the 'injuctive relief' would be, removal of the cross - no award fees what so ever, unless the losing party failed to abide by the court order.
Thanks for the info.
