A bankruptcy judge dismissed a 3M unit’s Chapter 11 case to resolve lawsuits over combat earplugs, concluding that it had no “valid reorganization purpose.”

U.S. Chief Bankruptcy Judge Jeffrey Graham, who heard dismissal arguments for three days in April in Indianapolis, found that 3M subsidiary Aearo Technologies, which is financially solvent, had no “valid reorganization purpose” to file for Chapter 11 protection last year.
