It’s not exactly the Montgomery bus boycott, and Elon Musk is no Rosa Parks, but Tesla is apparently engaged in a highly unusual act of corporate civil disobedience.

Ordered by Alameda County health authorities to keep its Fremont, California mega-plant shuttered, the company opened the factory over the weekend and started making cars. On Monday, its employee parking lot was reported to be almost full, suggesting a near-total reopening.

CEO Elon Musk had announced two days earlier that the company would be suing the county in federal court. That lawsuit hasn’t yet yielded any results, however. So far as it’s possible to determine, Tesla is knowingly and intentionally breaking the law.
