A case involving two Bangladeshi men who are seeking refugee status in Australia because they say they are gay has exposed a tricky legal area, raising the question of how a person can prove to a court they are gay.

The men's future is in limbo. The Refugee Review Tribunal found in November that the two men were not eligible for refugee status because they were not gay, as they had claimed. But this decision was overturned last month on appeal by the Federal Magistrates Court -- and it's thanks in part to a collection of homemade porn shots.
