The ruling is that constitutional amendments, as defined by their state constitution, must define which laws are being requested to change or delete. So that means citizens can’t ADD rights to the constitution, only remove rights or remove a prohibition to a right. I would be surprised if any other ballot initiative had been ruled invalid for this reason in the past, since it seems so intentionally arbitrary.

That said, It feels like it would be easy to find the laws that need to be red-lined to make this valid.
