A Connecticut woman disfigured by a friend’s pet chimpanzee in 2009 was denied permission Friday to sue the state for $150 million on her claim that officials knew the animal was dangerous but didn’t do anything about it.

The state claims commissioner released a five-page decision approving the state’s motion to dismiss Charla Nash’s claim, saying the law at the time allowed private ownership of chimpanzees and didn’t require officials to seize legal animals. The state generally is immune to lawsuits, unless allowed by the claims commissioner.
