The High Court of Justice on Thursday officially abolished the so-called “mehadrin” public buses operated by the Egged bus company, but it is far from clear that the ruling will put an end to the gender separation arrangement in which female passengers are frequently forced to sit at the back of the bus. According to Justice Elyakim Rubinstein, “There is a common understanding today that the operation of the buses as they were run until 2007 is forbidden. This is the current opinion of the Transportation Minister and, as the regulatory body, that is what he will instruct the public bus companies. For those who are not clear on this, we will say that a public transportation operator (like anyone else) may not tell, request or order women to sit in a specific place on the bus just because they are women, or to tell them how to dress, and they are entitled to sit anywhere they wish.”
The sticker translates:
Every passenger is entitled to sit anywhere he chooses (except for those places limited to persons with disabilities). Harassing a passenger in this matter could be a criminal offense.
So sit down and be quiet. Or just keep standing.
