According to Independent European Court of Justice ruled that all EU countries must recognize residency rights of gay spouses:
All European Union countries must recognise the residency rights of same-sex spouses, the EU's top court has ruled.
In a landmark ruling for gay rights in Europe, the European Court of Justice ruled Romania must grant residence to the American husband of a local man even though Romania itself does not permit same-sex marriage.
This suggests that all EU countries much perform some legal changes to obey this ruling. However, the end of the article shows some doubt:
Member states are in charge – but this is a useful clarification in terms of avoiding discrimination.
This opinion poll concerning same-sex marriage in Romania shows a solid majority against it, so any law change touching same-sex relations topic is a sensible manner.
Question: What does ECJ ruling about residency rights of gay spouses actually mean for the EU countries that do not recognize same-sex marriage? Does this mean just changing the law to allow the same residency rights without any other changes or is it more complicated than that?
