The feud between the founder of the popular Grotto Pizza chain and retired federal Judge Joseph J. Farnan Jr. has expanded from the Delaware Superior Court to the Court of Chancery.

After making fraud allegations against Farnan in a malpractice suit filed last fall against Duane Morris in the Superior Court, restaurateur Dominick Pulieri is now pursuing his own claims against the judge in Chancery Court in an effort to regain control of a Rehoboth Beach motel he sold to Farnan for $3.2 million in 2002.
