I wouldn't think there would be such a thing, really.
The Legislature presumably acts upon the will of the people and wouldn't be "activist" in how it goes about it's business in any meaningful sense. If the Legislature oversteps its bounds by enacting a law that, even if highly popular with the citizens, is contrary to the Cons ution, then the law should be declared uncons utional by the courts. That's part of the function of courts -- if courts did not do that, Legislatures would have no checks on their powers other than an executive possibility, which isn't always an assurance of balance.
