You're talking about the council and wesen law as a reason Nick and Juliette can't be together, but it was 'just' Wesenrein law, not the official one, that banned mixed marriages and the befriending of a grimm. And the Council knows in a way of the mixed relationship and the friendship (Alexander and the Anubis episode).

We already had a 'mixed marriage' in the Ziegevolk as lawyer episode (forgot the name...), remember? There it's been a Löwen and a Mausherz. Ok, it didn't end well for the Mausherz, but it seems it's not that uncommon to marry outside your wesen-bloodline.
