The Supreme Court is set to hear a challenge to the Affordable Care Act a week after the election. Health law expert Renée Landers told Boston Public Radio on Monday Trump’s nominee to the Supreme Court Amy Coney Barrett may undercut Obamacare if she’s on the bench.

“The serious question is whether she will view the decision she criticized in (a court opinion upholding the Affordable Care Act) as a precedent that should be honored and respected,” said Landers, “or whether she thinks there are overriding principals like her different view of the text that should cause the court to revisit the case’s precedent and overturn the statute.”

Landers is Professor of Law and Faculty Director of the Health  and Biomedical Law Concentration at Suffolk University School of Law.
