Avira- i’m not aware of your Mareh Makom from Rav Chaim, however i do know that Rav Ovadya, the spiritual leader of the Shas Party, and of Rabbi Deri, has an explicit Teshuvah writing that Dinah Dimalchusah applies to the Isreaeli goverment, and one can’t argue “Kim li”; and i would imagine that Rabbi Deri would be bound by this Psak.
Incidentally, Rav Moshe also held that taxes in Israel are binding.
Regardless of Dinah Dimalchusa, though, one of the most Chamur Aveiros in the Torah is Chillul Hashem. For a religious leader, representing Torah to be caught evading taxes, would, i imagine consitute a big Chilul Hashem (“See, those religious parties are dishonest also”).
I do not want to judge anyone; and i know Rabbi Deri has definitely done much good, but to pretend he did nothing wrong is a complete distortion of Yiddeshkeit.
