The Talmud dictates in several places (Bava Batra 54b, Nedarim 28a, Gitin 10b, Bava Kama 113a, and Bava Batra 55a) dina de-malkhuta dina, that the law of the land is the authoritative law for Jews in areas where it does not force Jews to violate Jewish law. In this sense, one may not jaywalk, speed, or cheat on their taxes and simultaneously claim that they are following Jewish law.
This is likely not surprising to most Jews, and is rarely the subject of debate, even in the most fundamentalist of Jewish communities (although there are some people who claim to be religious or observant while simultaneously denigrating the law of the land).
It does, of course, mean that there are conceivably instances when it would be a religious obligation to break the law of the land. For example, Jews in San Francisco would have been Jewishly obligated to violate the anti-circumcision legislation proposed there last year if it had passed.
And there are other instances when the law of the land is more permissive than Jewish law would be. For example, Jewish law has meticulous guidelines for what one may and may not say, whereas American law guarantees free speech. There are likely times when a person’s speech is not illegal under the law of the land, while it would be against Jewish law. In those cases, Jewish law would take precedence.
Additionally complicated is what to do when the law of the land holds up a higher moral standard than traditional Jewish law does. For instance, the major Jewish law codes do not explicitly forbid employment discrimination; in fact, the Torah legislates different rules for the treatment of Jewish and non-Jewish servants, and it suggests Jews may treat Jewish and non-Jewish workers differently. American anti-discrimination laws thus function as stringencies. In these types of cases, Jews should be more punctilious about following the law of the land so as not to give the impression that Jewish law makes Jews less moral than the surrounding culture; such an impression would be a hilul Ha-shem, a desecration of God’s name.
