The main purpose of this legislation is to amend the Americans with Disabilities Act of 1990. It aims to require individuals to go through certain administrative processes before they can file lawsuits related to accessibility issues on consumer-facing websites and mobile applications. The goal is to protect small businesses from what are seen as predatory lawsuits regarding website compliance. Key provisions of the legislation include a requirement for individuals to notify the owner or operator of a website or mobile application about any accessibility issues before filing a complaint.
