In a decision derided by the ACLU as “disappointing,” a federal judge on Wednesday ruled that the administration of President Barack Obama cannot be compelled by the court to hand over the full Senate Intelligence Committee report on CIA torture.

With a lawsuit citing the Freedom of Information Act (FOIA), the ACLU had sought to force the release of the full report, which totals nearly 7,000 pages.

The roughly 500-page, heavily redacted executive summary of the report was released last year. But the full inquiry, which many say offers an important window into a shameful chapter of U.S. history, remains concealed from the public.

U.S. District Court Judge James Boasberg, who was appointed by Obama, claimed in the ruling that the document is immune from FOIA laws as it belongs to Congress.
