The Attorney General of Israel, Avihai Mandelblit, has put an end to what was surely going to become both a spectacle, a ridiculous event, a provocation and fight. Mandelblit said that the Biirkat Kohanot event is not one recognized as a religious event because it is unknown and has never happened before and therefore has also never happened before at the Kotel.

So, in accordance with the laws and directives protecting the Jewish holy sites, this cannot be deemed a religious event and cannot take place at the Kotel.

whew. a fight over a stupid made-up event is the last thing we need.

I wonder if they will relocate it to a local synagogue or to the egalitarian platform, and then try in future years to get it approved, as by then it will have already happened and they might be able to claim it then as a religious event.
