Does the Senate outlaw other families?

[Krusader]

I've only seen the Roman families outlawed, when I played as Parthia. Otherwise, they have stuck together.

When I was playing as the Brutii the Scipii were outlawed after I started my march on Rome. Seems like they took the opportunity to snatch some land off the Julii whilst they were distracted by my legions.

In my finished Julii campaign, the three families got outlawed within 2 turns. The Brutii first, then the Scipii and Julii. According to the diplomatic scroll, we were all at war, although I hadn't attacked any of them (just shamelessly bribed a few Brutii cities ). I managed to get a cease-fire with the Scipii, and then an alliance in the next turn. I won before finishing the Brutii.

In my Julii campaign, all the Roman factions (including mine) where outlawed on the same turn. I remember hoping that maybe, If we were all bad guys now, we could get friends and together smack the cheeky Senate. Nope it didn't work.
