proposed tz changes for Israel, Mexico, Simferopol, etc.

Regarding the DST rules for Israel, I have not been able to find any corroborating evidence that this became official policy. The only story in the online newspapers (Jerusalem Post for example) on the subject was in early July 2000 which mentioned that the committee had made a recommendation, but that the head of the Intertior Department disagreed with the recommendation.  Since they found a committee meeting newsworthy, wouldn't they also cover the official passing of a law to change their clocks later this year?  I'm just curious if anyone else found any official corroboration of this change before you make this change to your tz database.
