To answer the question whether the Israel legal system is based on Jewish Law foundations we must examine the two main operative factors which affect and control the nature of that system, that is, the legislative activity of the Knesset and the judicial activity of the courts. The fact that Israel law recognizes, though to a limited extent, the principle of binding precedent renders the courts active participants in the law-making process. This freedom of activity is restricted and operates only within the framework of the provisions of existing positive law, but this framework is quite flexible, as we shall later have occasion to note. Such restriction does not exist at all with regard to the Knesset's legislative activity. The Knesset is the sovereign legislature, unfettered even by a Constitution, and is free to make such law as it deems fit. The question, therefore, is on what assumptions do the various elements—the Ministry of Justice, the Government and the Knesset—engaged in the legislative process, function generally with regard to the subserving sources and more particularly with regard to the manner in which the law of the State is to rest upon Jewish Law.
It is difficult from an examination even of a representative sample of enactments passed by the Knesset to affirm that a clear and consistent policy indeed exists in this important regard, but from time to time expression has been given by those concerned to some of these underlying assumptions and it is proper that we should glance at these.
