Abiding by Civilian Law
In general, there is a halachic principle called dina di-malkuta dina, which means that Halacha demands obedience to the laws made by civil authorities. However, it's important to note that this principle is limited and is discussed at length by the modern day Rabbinic authorities.
- The Gemara says Dina D'Malchusa Dina ("the law of the land is the law").
- Bava Basra 54b. The principle of dina di-malkuta dina is accepted as the halacha (Ritva Nedarim 28a says that there's no opinion in the Gemara that argues with it). Rambam Hilchot Gezelot 5:11 and Shulchan Aruch Choshen Mishpat 369:6 codify this principle as halacha regarding the taxes of the government.
