Enforcement of most of the new laws was enjoined by courts, but they became enforceable after Roe was overturned.[139] Thirteen states have trigger laws that will ban most abortions in the first and second trimesters if Roe is overturned.[140][141][142] The states with trigger laws are Arkansas, Idaho, Kentucky, Louisiana, Mississippi, Missouri,[143] North Dakota, Oklahoma,[144][145] South Dakota, Tennessee, Texas,[146] Utah, and Wyoming.[147] Nine states, among them Alabama,[nb 5] Arizona, Michigan, West Virginia, and Wisconsin, as well as the already mentioned Arkansas, Mississippi, Oklahoma, and Texas,[nb 6] never repealed their pre-Roe abortion bans.
