[2][3] In February 2022, Ali launched legal action against the Green Party alleging discrimination of gender-critical belief under the Equality Act 2010.

[7] Shahrar Ali has degrees in biochemical engineering (BEng) and philosophy (BA, MPhil, PhD) from the University of London.

[17] In January 2015, Ali released a statement with the party's leader Natalie Bennett and his co-deputy Amelia Womack condemning the Parliamentary candidate for Cambridge, Rupert Read.

In November 2015, Ali was selected to be the third candidate on the Green Party's London-wide list for the 2016 London Assembly election.

[29][30] Ali described the accusation as a "gross fabrication", telling the Evening Standard that it was "designed to stifle legitimate criticism of the Israeli government".

[32][33] The Jewish Chronicle also quoted the Green Party as saying it had been advised "informally" about Ali's speech in 2009 but that its processes for dealing with this at the time had been "inadequate".

[34] The party later clarified that no formal complaint of antisemitism was ever received and condemned "the way in which the statements provided were used to fuel further stories and negative comment".

[38] In September 2018, Ali called for an investigation into the suspension of a member who was suspended for saying that allowing trans children to transition was child abuse.

[39] In October of the same year, he spoke at the Green Party's conference to oppose adoption of the Working Definition of Antisemitism.

In February 2021, Ali proposed a motion opposing the Working Definition of Antisemitism, which he called "counterproductive on its own terms and inimical to free speech on the Israel-Palestine conflict".

In her statement, Berry cited unspecified spokesperson appointments as being inconsistent with her pledge to support trans equality.

[48][49][50] In July, the Young Greens of England and Wales passed a motion calling for Ali's appointment to be ended.

[55] On 9 February 2024, the Judge ruled that the Green Party had subjected Shahrar Ali to "unlawful discrimination" on grounds of his gender critical belief and he was awarded damages of £9,100 for injury to feelings.

[57][58][59] In September 2024, the Green Party was ordered to pay £90,000 to Ali, representing 60% of his legal costs in bringing the case.
