Taiwan's top judges have ruled in favour of gay marriage, paving the way for it to become the first place in Asia to legalise same-sex unions.
The highest court ruled that current laws preventing members of the same sex from marrying violated their right to equality and were unconstitutional.
It gave parliament two years to amend existing laws or pass new ones.
Wednesday's landmark decision came as the LGBT community faces increasing persecution in the region.
In a press release following the ruling, the court said that "disallowing two persons of the same sex to marry, for the sake of safeguarding basic ethical orders" constituted a "different treatment" with "no rational basis."
The court concluded that "such different treatment is incompatible with the spirit and meaning of the right to equality" as protected by Taiwan's constitution.
The court's ruling means Taiwan's parliament will have to amend existing laws or pass new legislation.
But it's still unclear how far parliament will go.
The LGBT community hopes legislators will simply amend the existing marriage laws to include same-sex couples, which would grant them the same rights enjoyed by opposite-sex couples, including in cases of adoption, parenting and inheritance - and making decisions for each other in medical emergencies.
However, they fear parliament won't do that and will instead pass a new law that recognises same-sex marriages but gives them only some rights, not equal treatment in all matters.
Religious and parents groups opposed to gay marriage say they will lobby parliament not to pass any laws on legalisation. They argue such an important matter that affects the whole of society shouldn't be decided by just a few grand justices, but by the people in a referendum.
Both sides will now focus their attention on persuading the legislators.
