CA SB1341

Requires plaintiffs or petitioners in CEQA judicial challenges to disclose the identity of any person or entity contributing $1,000 or more toward the costs of the action, with a continuing obligation to identify cumulative contributions reaching that threshold.

Requires disclosure of any pecuniary or business interest that contributors have related to the proposed project being challenged.

Allows plaintiffs to request court permission to withhold public disclosure of contributor identities if the court finds the public interest in confidentiality clearly outweighs the public interest in disclosure, with individuals contributing in personal capacity having the right to limit disclosure to in-camera court review.

Permits courts to compel compliance with disclosure requirements through various remedies, including dismissal of the action, and allows courts to use disclosed financial information when determining attorney fee awards.

Prohibits judicial challenges to housing projects that are included in previously approved plans or projects that completed environmental review, though this does not eliminate obligations for further environmental study on those projects.
