The Michigan Minority Supplier Development Council has filed a countersuit against Piston Group, alleging breach of contract and defamation in an ongoing legal dispute over the minority leadership of the auto supplier.
The two organizations have been sparring since last year over Piston Group's minority-enterprise business status — a valuable certification doled out and rescinded by the MMSDC.
The MMSDC pulled Piston Group's certification in February after it determined its CEO, former Detroit Piston Vinnie Johnson, did not run the day-to-day operations of his large supplier, which operates four subsidiaries — Piston Automotive, Irvin Automotive, the Detroit Thermal Systems joint venture with Valeo, and office furniture unit Airea.
To be certified, a company must be 51 percent majority-owned by a person of color, actively managed in day-to-day operations by a person of color and operate independently, according to the organization.
The heads of Piston Group's four divisions are white, which the MMSDC says violates its rules.
