Oklahoma Gov. Kevin Stitt signed an executive order on Monday halting the state from issuing nonbinary birth certificates.

The order mandates the Oklahoma State Department of Health (OSDH) to “cease amending birth certificates” in any way that is inconsistent with state law, and to “remove from its website any reference to amending birth certificates” that doesn’t align with state law.

Stitt further urged the Oklahoma state legislature to “immediately pass legislation that will clarify, to the extent necessary, that changes in sex or gender on a birth certificate, or a designation of non-binary is contrary to Oklahoma law.”
