Has this amendment has been found unconstitutional in other states?

Constitutional rights for victims of crime has never been found unconstitutional on the merits of the law. In Montana and Kentucky, the courts struck down versions of Marsy’s Law, not on the language, but based on the procedure by which they were passed. The procedure to pass a constitutional amendment is explained in each state’s constitution and varies drastically by state. In Iowa, a constitutional amendment has to pass through two consecutive General Assemblies with identical language. Then the proposal is placed on the ballot and Iowans decide. Nothing in the language of Marsy’s Law has ever been found to be unconstitutional by any court.
