The main purpose of the FCRA Liability Harmonization Act is to update the civil liability rules under the Fair Credit Reporting Act (FCRA) specifically regarding class action lawsuits. The goal is to create clearer and more consistent guidelines for how damages are calculated and awarded in cases where companies fail to comply with credit reporting laws. Key provisions of the Act include changes to how damages are determined for both willful and negligent noncompliance with the FCRA.
