 Another is to prevent legislators attaching an unpopular provision ("rider") to an unrelated popular one, whether in the hope of sneaking the unpopular one through, or in the hope of causing the popular one to be rejected (a type of wrecking amendment).In English law, the long title of a bill or act of parliament states its purpose; this may enumerate multiple purposes, or end with a vague formula like "and for other purposes".A proposed amendment to a bill may be rejected if it is outside the scope defined in its long title; alternatively, the title may be amended to increase its scope.
