## Facts

- The City of Naperville owned and operated the Naperville Department of Public Utilities–Electric, the local provider of residential electric service.
- The City instituted the “Naperville Smart Grid Initiative,” replacing analog meters with wireless smart meters.
- Analog meters were read about once per month and yielded a single monthly consumption figure; smart meters recorded aggregate electricity usage in 15-minute intervals, generating thousands of readings per month.
- Naperville Smart Meter Awareness (NSMA), an Illinois nonprofit organization formed by residents opposed to the smart-meter program, sued the City under 42 U.S.C. § 1983.
- NSMA alleged the City’s collection of high-frequency usage data could reveal details about in-home life (such as occupancy patterns and appliance use), and therefore constituted an unreasonable search.
- The district court had previously dismissed NSMA’s Fourth Amendment challenge to aggregate electricity-usage data in earlier pleadings.
- NSMA moved for leave to file a Third Amended Complaint, alleging additional facts, including that the City had access to “energy disaggregation” software capable of deriving more granular information from the 15-minute interval data.
- The proposed Third Amended Complaint asserted: (i) a Fourth Amendment unreasonable-search claim, (ii) a parallel claim under Article I, § 6 of the Illinois Constitution, and (iii) an equal protection claim alleging the City permitted some residents to keep analog meters while denying NSMA members that option.

## Issues

1. Whether amendment would be futile because the proposed Third Amended Complaint still failed to state a plausible Fourth Amendment unreasonable-search claim based on the City’s collection of smart-meter electricity-usage data.
2. Whether amendment would be futile because the proposed Illinois Constitution Article I, § 6 claim (privacy/unreasonable search) was inadequately pleaded.
3. Whether amendment would be futile because the proposed equal protection claim failed to plausibly allege disparate treatment of similarly situated residents without a rational basis.
4. Whether NSMA adequately alleged associational standing to pursue injunctive relief on behalf of its members.

## Decision

- The court granted in part and denied in part NSMA’s motion for leave to file the Third Amended Complaint.
- The court denied leave to amend as to the Fourth Amendment claim, concluding the proposed allegations still did not state a plausible unreasonable-search claim and therefore amendment was futile.
- The court denied leave to amend as to the Illinois Constitution Article I, § 6 claim for similar reasons.
- The court granted leave to amend as to the equal protection claim, finding the allegations of disparate treatment regarding retention of analog meters sufficient to proceed at the pleading stage.
- The court held NSMA adequately alleged associational standing to seek injunctive relief on behalf of its members.

## Legal Principles

- Leave to amend under Federal Rule of Civil Procedure 15(a)(2) should be freely given, but may be denied where amendment would be futile because the proposed claims would not survive a Rule 12(b)(6) motion.
- Under Rule 12(b)(6), a complaint must plead enough factual matter to state a claim that is plausible on its face; labels and conclusions are not enough.
- Fourth Amendment “search” analysis turns on whether the government action intrudes on a reasonable expectation of privacy; information voluntarily conveyed to a utility in the course of receiving service may be treated as the utility’s business records rather than the customer’s private papers.
- Consent and voluntary disclosure principles may defeat a claimed expectation of privacy where customers accept service with knowledge that usage will be measured and recorded for billing and operations.
- Illinois Constitution Article I, § 6 can, in some contexts, be interpreted more broadly than the Fourth Amendment, but a plaintiff must plead a viable basis in Illinois law for different treatment; otherwise, the state claim may rise or fall with the federal analysis.
- For equal protection claims outside a suspect class, rational-basis review applies; a plaintiff must plausibly allege differential treatment of similarly situated persons and facts permitting an inference that the disparity lacked a rational governmental reason.
- An organization may sue on behalf of its members (associational standing) where members would have standing, the interests at stake relate to the organization’s purpose, and the claim for injunctive relief does not require individualized member participation.

## Conclusion

The court treated NSMA’s added allegations about data granularity and disaggregation technology as insufficient to revive its Fourth Amendment and Illinois constitutional search/privacy theories, denying leave to amend those counts as futile, but allowed NSMA to proceed on an equal protection theory based on alleged disparate treatment in permitting some residents—though not NSMA members—to retain analog meters.
