A man facing a charge in the Selangor Syariah High Court for allegedly attempting to commit unnatural sexual intercourse, has been granted leave by the Federal Court to commence a constitutional challenge on a provision in the Selangor Syariah law which he was charged under.

We unpack what this all means, while discussing the implications of this landmark case, and the grounds on which the Federal Court has granted leave to the petition in the first place.
