UTILITY RATE INCREASE CAP

Amends the Public Utilities Act. Prevents the Commission from approving any increase in rates by a water or sewer service of greater than 15%. Requires these utilities to include notice of any proposed rate change on every bill sent to customers until the rate change is approved or denied. Allows customers who have had their rates increased by over 15% to file a civil action against the utility for damages in which the customers are certified as a class, are granted a rebuttable presumption that any increase in excess of 15% is unjustified, and are entitled to double damages as well as attorney's fees and costs. Entitles customers that have filed a class action against a water or sewer service utility for increasing their rates by over 15% to a temporary restraining order halting collection of the increase until the civil action is resolved.
