Is the Diocese of Wheeling/Charleston Planning to Oppose Parental Rights?

This morning I received an email from Michael Hichborn of the Lepanto Institute describing how the Diocese of Wheeling/Charleston plans to join a lawsuit against the state over a bill giving parents the freedom to choose vaccinations for their children. If true, it's a shocking position! 

Does a Catholic Diocese have more rights over children than their parents? Not according to canon law.
