Parties objecting to the Boy Scouts of America’s bankruptcy plan have filed the first briefs in their appeal to the District of Delaware, again arguing the plan cuts off the rights of both insurers and sex abuse claimants who hope to pursue other litigation.

The BSA now has until Dec. 7 to respond to the allegations raised in four briefs Monday by parties whose appeals were consolidated by U.S. District Court Judge Richard G. Andrews after being filed in late September, soon after the Delaware bankruptcy court approved a final Chapter 11 plan.
