The Supreme Court has ruled that the anti-LGBT hate group Liberty Counsel must refer to Gavin Grimm as a male.

Liberty Counsel, who previously represented Kim Davis, had been actively trying to change Grimm’s pronouns throughout the case so far.

The ACLU, who are representing Grimm, posted a letter on twitter that was written to Mat Staver, chairman of the Liberty Counsel yesterday.

The letter, from the Supreme Court, instructs the Christian law firm to refer to Grimm as male.

“It has come to the attention of this office that the cover of your amicus brief in this case identifies the respondent as ‘G.G., by her Next Friend and Mother, Deirdre Grimm.’ In fact , the caption for the case in this Court, as in the lower courts, identifies the respondent as ‘G.G., by his Next Friend and Mother, Deirdre Grimm.

“Please ensure careful compliance with this requirement in this and other cases in the future,” the letter concludes.

Grimm sued the Gloucester County School Board with ACLU after the board enacted a police that ordered trans students to use the toilet that corresponded with their “biological gender”.

Grimm claimed this infringed on the rights of trans people and after a long court battle, it is not set to be heard by the Supreme Court.

The lawsuit has become high profile in America, with celebrities such a Laverne Cox calling for people to become educated on the case.

Trump’s administration has just revoked trans bathroom protections, bringing even more weight to the case.
