Some idiot sued the Rabbanut in the Israeli High Court, demanding that the High Court order the Rabbanut to explain why it can’t declare a leap year.
The plain fact is that Ibur Hashana can ONLY be done by the Sanhedrin, or a beis din authorized by the Sanhedrin. And the only way we get a Sanhedrin back is by Eliyahu coming and giving them smicha. In which case our problems will be solved and we may not need the extra month.
