One of the comments on the article stated that it could have taken 3 years to proceed with the lawsuit, i'm not familiar with anything like this so couldn't say for certain.
Also, I wouldn't wonder if Disney might give a sum of money as a goodwill gesture. Not saying whether they should or shouldn't but it wouldn't be the first time a company has done so even if they're not at fault for an incident, one that springs to mind is the Brittney Bergeron case (tons on google about it)
