A federal judge temporarily blocked enforcement of a section of the National Defense Authorization Act that opponents claim allows for indefinite military detention.

The plaintiffs contend a section of the law allows for detention of citizens and permanent residents taken into custody in the U.S. on “suspicion of providing substantial support” to people engaged in hostilities against the U.S., such as al-Qaeda.

Hedges said he could be held in custody by federal authorities just for interviewing such individuals, according to court filings. Forrest’s order prevents enforcement of the provision of the statute pending further order of the court or an amendment to the statute by Congress.
