The Trump administration has made an emergency request to the US Supreme Court to allow restrictions on transgender inmates’ medical care in federal prisons. The filing came on September 28-29, according to Reuters and AP.

The administration wants the court to lift lower-court orders that blocked its limits on gender-affirming care for prisoners. The case could set a major precedent on the medical rights of inmates.

Transgender prisoners have challenged the policy in court, arguing it denies them medically necessary treatment. Lower courts sided with the inmates and barred the restrictions.

The government argues that prisons should control their own medical policies and costs. Rights groups call the move discriminatory and say it endangers vulnerable prisoners. Legal experts say such emergency requests are rare and often signal a fast decision.

The Supreme Court has not yet said when it will rule on the emergency request. Its decision could affect transgender inmates across the federal prison system and shape similar state-level battles.
