WASHINGTON — The Supreme Court on Monday let stand an appeals court ruling shielding the documents of a Planned Parenthood affiliate in New Hampshire from an anti-abortion group’s request under the open records law. As is its custom, the Supreme Court gave no reasons for turning down the appeal in the case.

Justice Clarence Thomas, joined by Justice Antonin Scalia, dissented, saying disagreements in the lower courts over the scope of the open records law, the Freedom of Information Act, warranted Supreme Court review.

The case, New Hampshire Right to Life v. Department of Health and Human Services, No. 14-1273, followed New Hampshire’s decision in 2011 to stop awarding money to Planned Parenthood of Northern New England after officials expressed concern that taxpayer funds were being used to subsidize abortions. The group then applied for federal money from the Department of Health and Human Services, submitting various documents in support of its request, including ones on medical standards, fees and personnel policies.

After the request was approved, New Hampshire Right to Life, an anti-abortion group, asked the government for the documents under the open records law.
