DeNittis said both plaintiffs — John Farley, of Evesham and Charles Noah Pendrack, of Ocean City — came to him after reading last week about the short sandwiches.
DeNittis is asking for compensatory damages for his client and a change in Subway’s practices.
The Milford, Conn.-based firm should either make sure its sandwiches measure a full foot or stop advertising them as such.
He points to how McDonald’s quarter-pounders are advertised as being that weight before they are cooked.
Subway did not immediately return a call to The Associated Press on Wednesday.
