irreparable damage or injury
n. the type of harm which no monetary compensation can cure or put conditions back the way they were, such as cutting down shade trees, polluting a stream, not giving a child needed medication, not supporting an excavation which may cause collapse of a building, tearing down a structure, or a host of other actions or omissions. The phrase must be used to claim that a judge should order an injunction, writ, temporary restraining order or other judicial assistance, generally known as equitable relief. Such relief is a court order of positive action, such as prohibiting pollution or requiring the shoring up of a defective wall.
