This is how it usually works: clients supposedly have 7 days after the contests end to make a choice but the site administrator actually gives them 2 weeks. Once that period is over if the client has not acted yet the administration will review the case and either award the prize to the existing #1 design themselves or if it is not clear (for example if a client did not rank at all or hasn't done so in days) there might be a community vote to decide who wins. My advice for you is to let one of the moderators and the administrator, Tyler, know about it if a contest you have taken part in has been in judging mode for days without the client logging in or taking any action and they will get back to you.
