[Star Wars] Does Darth Vader ever have to attend state functions in his role in the Empire?

Like does Vader show up at signings of new laws, or commissioning of big projects? How about state funerals?

I don't think so. Vader is not really a public official. He has what Tarkin refers to as "invisible rank" (I think that was the term he used). 

He's basically the Emperor's enforcer. He shows up when stuff needs to get done, not to cut ribbons. Also, it seems sort of counterproductive to have him in the public light at all times. He's supposed to be feared, so you don't want to get the public too used to him.
