The three phases of the policy debate in order are constructive, cross-examination, and rebuttal.
Explanation:
Constructive: each side performs their opinion for or against the resolution. The first constructive are normally prewritten.
Cross-examination: supporting each effective speech is a short question-and-answer session. The debater asking questions is generally given control over the cross-x.
Rebuttal: each side counters to the evidence of the defense and crystallizes their own cases. Normally uniquely new proof/arguments are not deducted in these speeches.
