Not. Two of the three branches of state government agree on a course of action. That is sufficient to overrule the wishes of the single "judicial" branch. Otherwise, the three branches are not "co-equal". Jeb Bush is a wuss.
So a vote by both houses of the California Legislature and a signature by Ah-Nold on a bill to set aside the jury's decision and declare OJ Simpson guilty of murder is perfectly legal? If not, then the branches aren't "co-equal", are they?
A majority of the Supreme Court and Congress can declare that President Bush isn't C-in-C of the Armed Forces any longer, but he has been replaced by Pee-Wee Herman? 2 out of three, not "Co-Equal" otherwise!
You appear to have a grossly distorted view of Separation of Powers.
