When can you file a Rule 12(b)(6) Motion?

• A. before you answer
• B. after you answer
• C. after discovery
• D. during trial

Answer: (A)

The key concept is that a Rule 12(b)(6) dismissal for failure to state a claim is an early-pleading defense. It is designed to screen out legally insufficient claims before parties incur discovery costs, so it is raised before the defendant files an answer. That timing matters because once an answer is filed, the opportunity to raise this specific defense is typically waived under the rules (you must raise it in a pre-answer motion or in the first pleading). Waiting to raise it after discovery or during trial would not be appropriate, since the purpose of the motion is defeated if the case has already progressed. Note there are some exceptions for certain defenses (like lack of subject-matter jurisdiction) that may be raised later, but for the standard failure-to-state-a-claim defense, the correct approach is to file before you answer.
