Liberal Justice Sonia Sotomayor said on Thursday the U.S. Supreme Court’s “mistakes” in high-profile cases can be corrected over time as she adopted a positive tone ahead of a decision in which its conservative majority is expected to curtail abortion rights.

Sotomayor, speaking in Washington at the annual meeting of a liberal legal group, did not directly address last month’s publication of a leaked draft opinion in the abortion case or any of the court’s other current cases. But Sotomayor said she believes the court can help people “regain the public’s confidence” in government institutions.

The leaked draft ruling, authored by conservative Justice Samuel Alito, indicated that the court’s conservative majority is set to overturn the landmark 1973 Roe v. Wade ruling that legalized abortion nationwide. The court has a 6-3 conservative majority, with Sotomayor one of three liberal justices.

“Institutions are made up by humans. Because we are human, by necessity we make mistakes. It is the nature of the human enterprise,” Sotomayor told the American Constitution Society meeting.
