Arizona still has laws on the books that outlaw abortion and impose tough mandatory prison time.

Despite the 1973 Roe v. Wade Supreme Court decision, the state never repealed those abortion laws, some of which date back decades before the landmark legal ruling.

Now activists worry those laws could once again be enforced should President Donald Trump's nominee to the Supreme Court rule with enough justices to allow states to outlaw abortion.

"One could argue that those laws remain enforceable if Roe v. Wade was overturned," said Arizona State University law professor Stefanie Lindquist.

One law that's still a part of Arizona's statutes, but unenforceable right now, mandates that anyone caught providing an abortion would spend two to five years behind bars.

Lindquist says state lawmakers may decide to revalidate the laws or a prosecutor like a state attorney general or county attorney could try to prosecute someone.

"The law, even if there was a challenge to its validity because it was old and an intervening precedent had somehow invalidated it, the Legislature could easily revalidate it," Lindquist said.
