In the Parliament of the United Kingdom, a reasoned amendment is an amendment to the wording of the motion on the reading of a bill, which turns the motion from one progressing the bill into one rejecting it. It is sometimes called a wrecking amendment, but the term wrecking amendment more often denotes a type of amendment to the bill itself, rather than to a motion on reading the bill. The term "reasoned amendment" reflects the fact that the amended motion specifies reasons for rejecting the bill.[1][2]
