The action comes after days of protests by lobster fishermen, who have been blocking truckloads of cheap American lobster from being processed at plants across the province.
The fishermen say the market glut has driven the price down to about $2 per pound which is a 30-year low. They say they need at least $4 to survive.
The Maritime Fishermen's Union and "persons unknown" are named as the respondents in the documents, filed with the Court of Queen's Bench in Moncton.
The details of the action are unknown because the documents were in a judge's chambers Thursday morning, but a court appearance is scheduled for 2 p.m.
Processors Cooperative des Pêcheurs de la Baie Ste. Anne, Cape Bald Packers, Captain Dan's Inc., Crown Seafood Ltd., and Shediac Lobster Shop et al are the complainants named in the documents.
The lobster season on the Northumberland Strait, which was scheduled to begin Thursday, has been delayed by the federal Department of Fisheries and Oceans until Monday at the request of the fishermen.
They are expected to meet with the federal and provincial fisheries ministers on Friday.
