Whether the district court could refuse to reach the vagueness claim because plaintiffs had not expressly pleaded it in their First Amended Complaint.
Holding
No. The district court abused its discretion by failing to construe plaintiffs’ summary-judgment arguments as a request to amend the pleadings and by refusing to decide the vagueness claim on the merits.
Reasoning
Federal Rule of Civil Procedure 15 embodies an extremely liberal amendment policy. When a claim outside the pleadings is raised in connection with summary judgment, the district court ordinarily should treat the matter as a request to amend, particularly where the opposing party can fully litigate the issue.
The record did not support bad faith or undue delay. Plaintiffs learned the critical details of the LAPD’s enforcement policies only when the City produced internal memoranda eight days before discovery closed. Those materials mattered because a vagueness analysis considers whether an enforcement agency has adopted a limiting interpretation that gives the law definite meaning.
The City was not unfairly surprised or prejudiced. Plaintiffs’ deposition questions focused on the absence of concrete enforcement criteria, plaintiffs told defense counsel before summary judgment that they would assert vagueness, and both sides fully briefed the issue. No additional discovery was needed, the amendment was not futile, and plaintiffs had amended only once before receiving the late-produced materials.
