How can a constitutional amendment be unconstitutional? It’s part of the constitution!!
The California constitution allows for “Amendments” to be placed on the ballot by initive, like Prop 8. “Revisions” must be placed on the ballot by 2/3 of the legislature. The suit says it should have been a revision, not and amendment, so it’s not legally part of the constitution. The court has decided twice before in the last 100 years that constitutional ammendments voted on were extensive enough to be revisions and overturned them.
