[Harry Potter] What would have happened if Harry hadn't taken part in the Triwizard Tournament?

I know that it is a binding magical contract, but I can't find anywhere what would've happened to Harry if he decided not to participate?

We don't know. It's never explained. But given that the entire faculty and Ministry of Magic nevertheless let/forced Harry to participate, we can infer that violation was either impossible or that the consequences for doing so were more severe than anything that could have (reasonably) happened in the course of the Tournament.
