While attorneys representing the diocese claimed the lawsuit was barred by the ecclesiastical abstention doctrine, which prevents secular courts from becoming involved in religious affairs, Sasser disagreed.

Gallagher’s defamation lawsuit “can be assessed using neutral principles of law and without resolving a church controversy,” she wrote.

Coral Gables attorney Joseph Winsby, who is representing the diocese, wasn’t immediately available for comment.

Attorney Ted Babbitt, who is representing Gallagher, said he expects Winsby will appeal Sasser’s ruling. But Babbitt said he hopes to begin preparing for trial. His first task will taking a deposition of Barbarito. He said he expects the church to challenge those plans as well.

Gallagher, a former pastor at Holy Name of Jesus Catholic Church, sued the church in January. He claimed Barbarito punished him for ignoring instructions not to tell authorities that the Rev. Jose Varkey Palimattom, a visiting priest, had shown pornographic pictures to a 14-year-old youth at the suburban West Palm Beach church in January 2015.

After working with the Palm Beach County Sheriff’s Office to help prosecute Palimattom, Gallagher claims he was locked out of the rectory and the church.

In court papers, Winsby disputed Gallagher’s assertions. “This incident was reported by the diocese to law enforcement immediately and no cover-up was accomplished,” he wrote.

However, Winsby said, how the diocese handled Palimattom and Gallagher are rooted in church policies and procedures.

“These questions inextricably intertwine church discipline, ecclesiastical government, and the conformity of the members of the church to the standard of morals required,” he wrote. “A jury should not consider those issues pursuant to the First Amendment to the United States Constitution.”
