Budweiser outlawed in Portugal

The EU Court Of Human Rights (huh?) has ruled that Anheuser-Busch can't sell beer in Portugal under their long time Budweiser label. How is it that the jurisdiction of a so-called human rights court covers anything about trademarks? Is it a human right to drink beer with a certain name?

It's nice to know that the Eu Court of Human Rights is on the case. We wouldn't want them to waste their time on trivial matters, like honor killings of women, now would we?
