Normally, this decision to repeat the election affects only the MPs elected in the constituency where the new vote is required, but it doesn’t have to affect the MPs elected in other constituencies. The problem arises when there is a single national constituency, which is the case of Serbia. In this case, when it’s not possible to certify the result, the Parliament cannot be constituted. Even the formation of the government may be paralysed, although a technical, transitional, or caretaker government is usually well-positioned to deal with day-to-day business.
