From the article:

    Beckerman, in the 25-page written ruling, declared that
    Järlström may study and, communicate publicly or privately
    about his theories relating to traffic lights, as long as
    his remarks occur outside the context of any employment or
    contractual relationship with a governmental or other
    group that regulates traffic light-timing.

I'm guessing this means that it's not calling yourself a doctor, but practicing medicine without a license that'll get you in a whole heap of trouble.
