The organization filed a petition Thursday asking the high court to find the law unconstitutional without letting any lower courts rule first. Liberals hold a 4-3 majority on the Supreme Court, and one justice has repeatedly declared her support for abortion rights.

Planned Parenthood of Wisconsin asked the state Supreme Court on Thursday to overturn a 174-year-old state law that conservatives have interpreted as an abortion ban. It’s the second legal challenge to the statute since the U.S. Supreme Court invalidated Roe v. Wade.

The organization filed a petition asking the high court to rule the law unconstitutional without letting any lower courts rule first. And if the justices do so, Planned Parenthood will consider challenging other restrictions on abortion found throughout state law, including bans based on fetal viability and parental consent mandates, according to the organization’s chief strategy officer Michelle Velasquez.

“This petition is really asking whether the Constitution protects access to abortion,” Velasquez said during a video news conference. “We’re asking the court to basically say laws related to abortion would be subject to the highest level of scrutiny.”
