Everything about Israel is like that - takes forever and lots of graft and bribery. We in the west think they much be first world country but they are much more like a third world / middle east country. Try collecting overpaid taxes back from the Israel Tax Authority if you are a US citizen - even a bigger nightmare.
What more time they need to make a ruling in this case is unfathomable. Unless they know by law they have to rule in favor of Sun but they want to rule in favor of Taro being Israeli. So there's the dilemma.
