A bill that would take off the books an unconstitutional creationism law died on the state Senate on Monday.

Only five senators voted for the measure while 32 voted against it.

State Sen. Dan Claitor, R-Baton Rouge, sponsored repeal of the Creation Science and Evolution-Science Act.

Similar legislation cleared the Senate last year but died in a House committee.

The 1981 law was found unconstitutional on 1987 by the U. S. Supreme Court.

Claitor’s bill is separate from a proposal that would repeal a state law that allows school districts to use supplemental materials in the teaching of evolution and certain other topics.

Backers say that law is designed to spark wide-ranging classroom discussions.

Opponents say it allows for the teaching of creationism.

That measure is pending in the Senate Education Committee.
