An Arizona law that would grant personhood to fetuses, embryos, and fertilized human eggs was challenged in court again, and on Monday a District judge blocked the law.

U.S. District Judge Douglas Rayes said in his ruling that the law appears to be vague. He said, “When the punitive and regulatory weight of the entire Arizona code is involved, Plaintiffs should not have to guess at whether their conduct is on the right or the wrong side of the law.”
