CA SB1052

Requires plaintiffs or petitioners in CEQA lawsuits to disclose their name and city/county of legal residence in the complaint or petition.

Mandates disclosure of the identity and contribution amount of any person or entity contributing more than $100 toward the plaintiff's legal costs, whether as cash, services, or contingent contributions.

Requires plaintiffs to identify any pecuniary or business interest related to the project held by named parties or financial contributors to enable courts to assess the appropriateness of attorneys' fees awards.

Failure to provide required disclosures constitutes grounds for dismissal of the action, or if noncompliance occurs after judgment, results in denial of attorneys' fees for the prevailing party.

Allows courts to prohibit disclosure of financial contributors in public pleadings upon request, weighing public interest and private attorney general principles.
