The Law of Return (חוק השבות, ḥok ha-shvūt) is an Israeli law, passed on 5 July 1950, which gives Jews, people with one or more Jewish grandparent, and their spouses the right to relocate to Israel and acquire Israeli citizenship. Section 1 of the Law of Return declares that "every Jew has the right to come to this country as an oleh [immigrant]". In the Law of Return, the State of Israel gave effect to the Zionist movement's "credo" which called for the establishment of Israel as a Jewish state. In 1970, the right of entry and settlement was extended to people with at least one Jewish grandparent and a person who is married to a Jew, whether or not they are considered Jewish under Orthodox interpretations of Jewish law. On the day of arrival in Israel, or occasionally at a later date, a person who enters Israel under the Law of Return as an oleh would receive a certificate confirming their oleh status. The person then has three months to decide whether they wish to become a citizen and can renounce citizenship during this time. The right to an oleh certificate may be denied if the person is engaged in anti-Jewish activity, is a hazard to the public health or security of the state, or has a criminal past that may endanger public welfare. The Law of Return was passed unanimously by the Knesset, Israel's Parliament, on 5 July 1950. The date chosen so that it would coincide with the anniversary of the death of Zionist visionary Theodor Herzl. It declared: "Every Jew has the right to come to this country as an oleh." In a declaration to the Knesset, the then Israeli prime minister David Ben-Gurion asserted that the law did not bestow a right but rather reaffirmed a right Jews already held: "This law does not provide for the State to bestow the right to settle upon the Jew living abroad; it affirms that this right is inherent in him from the very fact of being a Jew; the State does not grant the right of return to the Jews of the diaspora. This right the State; this right the State; its source is to be found in the historic and never broken connection between the Jewish people and the homeland.
