After Tesla this week objected to a regional National Labor Relations Board ruling that it violated federal labor laws and engaged in anti-union activity, the case goes to the NLRB in Washington, D.C.

The Palo Alto company filed 166 exceptions to a September decision by Amita Baman Tracy, an NLRB Administrative law judge in California.
