(Reuters) - Tesla Inc has filed an appeal on a U.S. National Labor Relations Board ruling that the electric-car maker had violated U.S. labor law, and on the agency’s order that Chief Executive Officer Elon Musk delete a tweet from the account.

The electric-car maker filed a petition on Friday with the New Orleans-based U.S. Court of Appeals to review the NLRB’s decision and order issued on March 25.
