>Finally, I wish to impress upon any of you wishing to compete that this Tournament is not to be entered into lightly. Once a champion has been selected by the Goblet of Fire, he or she is obliged to see the Tournament through to the end. The placing of your name in the Goblet constitutes a binding, magical contract. There can be no change of heart once you have become champion. Please be very sure, therefore, that you are whole-heartedly prepared to play, before you drop your name into the GobletThis is why Voldemort's plan is quite excellent. He told Karkaroff to just magic the step where it spits out the name of the participant, thereby forcing Harry to abide by the contract. The Goblet presumably does not care how the name got in and why it spits one out, it just cares that whoever names it spits out *must* participate and play in triwizard tournament or face the consequences (either lose their magic forever or death, taking examples from other type of magical contract like the Unbreakable Vow)
