Transgender Kansas residents have begun receiving letters from the state’s department of motor vehicles notifying them that their driver’s licenses will be invalid beginning Thursday, as a new law goes into effect that demands that forms of identification must now reflect the credential holder’s “sex at birth”.

The bill, known as SB 244, also bans transgender people from using bathrooms in public buildings that match their gender identity, and creates a sort of bounty hunter system, in which citizens can sue transgender people they encounter in restrooms for $1,000 in damages.

The state law was rushed through the state legislature using an expedited procedure known as “gut and go”. This means the text of one bill can be taken out and substituted for entirely new language or provisions, bypassing standard committee vetting and speeding through the voting process, which is legal in Kansas.

Governor Laura Kelly, a Democrat, vetoed the bill, arguing that SB 244 was “poorly drafted legislation”, but her veto was overridden by the state legislature’s Republican supermajority.
