Is suspending judgement a way to avoid wrong view?

I came to this question from a comment made on an answer to a question about belief in rebirth. The comment read: "A view that rebirth does not exist is a wrong view. You cannot realize Nibbana with this wrong view." Now I wanted to reply that suspending judgement is a form of avoiding wrong view, but then I realized I'm not really sure; which bothered me. I suspend judgement about a lot of things even to the point of whether Buddhist enlightenment is real. So is suspending judgement proper, or does one on the Buddhist path eventually have to make choice?
