Catholics do, ultimately have a say in the governance of their Church--at least when it comes to the business end of things.  If a pastor at a parish is not working out, or blowing through money, etc, eventually the bishop will reassign him.  It is just that trustees and elders do not have the authority to fire him based on their personal whims at the time.   

I have seen how ruthless boards of elders and trustees can be to their ministers.  I have seen this in both the Methodist and Presbyterian churches. There is one Methodist Church where it was like a revolving door when it came to the ministers.  I wondered why the superintendent did not eventually stand up to them and tell them to live with the minister or they are not getting another one.

When it comes to doctrine, ultimately the bishops have final say, true, but this is not to say that the Faithful are irrelevant when it comes to doctrine.  They just don't have the ultimate say.
