This law protects Missouri website owners from lawsuits that are mainly filed to make money off legal defense costs rather than to actually fix accessibility problems. If someone gets written notice that their website has an accessibility problem and takes real steps to fix it within 90 days, there is a legal assumption that any lawsuit filed anyway is abusive. A Missouri resident or the attorney general can go to court to fight back against these kinds of lawsuits. If a court agrees the lawsuit was abusive, the person who filed it may have to pay the other side's legal fees and possibly extra money on top of that.
