The headline for an article in today's New York Times reads: "Court Ruling Could Make Taiwan First Place in Asia to Legalize Gay Marriage"
My question is whether this can truly be considered "legalization." This seems to be the case based on the definition of the word:
to make legal; especially : to give legal validity or sanction to
But for some reason I have the feeling that only those with legislative power (rather than interpretive power) can truly "legalize" something. I would argue (not very confidently) that if a court decides that something is legal based on interpretation of the currently existing laws, than that thing in some sense has always been legal. I think I'm wrong about this, but I just want to make sure.
