Hm. I don't actually know what you are referring to.

Are you talking about any specific incident or event? Any particular time period? Any specific province?

Are you referring to the Roman Empire (I.e. the time after Augustus, when Rome was ruled by an emperor) or do you perhaps mean the time of the Republic? The senate continued to exist in the Roman Empire, but it didn't make many important decisions anymore... at least without prompting from the emperors. But the Senate did still provide many provincial governors.

So: We'll need you to provide some more information so we can be sure what it is you're actually asking. As is, I doubt anyone will be able to help you.
