MIAMI, Aug 30 (Reuters) – A Caribbean regional court has ruled that a Saint Kitts and Nevis prohibition on gay sex is unconstitutional because it violates the right to privacy, striking down one of a handful of bans on same-sex intercourse that still exist in the region. The Eastern Caribbean Supreme Court ruled against two portions of the Offences Against the Person Act, adopted in the dual-island nation in 1873, which called for up to ten years imprisonment for having or attempting to have gay sex.
