Basic Law: The Knesset

The law identifies the Knesset as the State's parliament, sets its membership at 120, and places its seat in Jerusalem.[2] The original law did not comprehensively define the Knesset's powers, but it established the institution's basic framework and regulated elections, voting and candidacy, terms of office, parliamentary immunity, the Knesset buildings, and the work of the Knesset and its committees.[6][3]

Section 4 provides that Knesset elections are "general, national, direct, equal, secret and proportional."[2] In practice, Israel constitutes a single electoral district; voters choose party lists directly; each vote has equal weight and participating lists must receive equal opportunity; secrecy protects voters from pressure; and seats are allocated proportionally among lists passing the electoral threshold.[7] Section 4 may be varied only by a majority of all Knesset members—61 of 120—and early litigation treated its entrenched requirements as normatively superior to conflicting ordinary legislation.[2][8]

Israeli citizens aged 18 or older generally have the right to vote, while the minimum age for election is 21.[2][7] Certain officeholders—including the State President, judges, the State Comptroller, the IDF Chief of the General Staff, chief rabbis, and specified senior public servants and military officers—may not stand while occupying their positions.[2] Criminal convictions can also temporarily restrict candidacy, with a longer exclusion period applying to serious terrorism or security offenses.[7][9]

The regular Knesset term is four years. Section 9 sets the ordinary election date as the third Tuesday of Cheshvan in the final year of the term, or the first Tuesday if the preceding year was a leap year.[10][7] The Knesset may dissolve itself through legislation supported by a majority of its members, while an extension of its term requires 80 members and special circumstances that prevent elections from being held on time.[11][10] In 1973, before the current extension provision existed, elections scheduled for October 30 were postponed to December 31 after the Yom Kippur War began; the special postponement law passed 67 to 1.[10]

Members must declare allegiance to the State and faithfully discharge their mandate before enjoying the full rights of membership.[2] The law provides for a Speaker, vice-speakers, permanent and special committees, and commissions of inquiry that include proportional representation for parliamentary groups outside the government.[2] It also establishes public sittings as the default, protects open-session proceedings subject to restrictions governing closed or protected material, grants immunity to members and the Knesset building, and bars emergency regulations from varying or suspending the Basic Law.[2]

Israel's Declaration of Independence envisaged a constitution to be adopted by an elected Constituent Assembly. Elections for that assembly were held in January 1949, but the body renamed itself the First Knesset and did not adopt a complete constitution after extended debate over the form and timing of such a document.[8][12]

The resulting compromise was the Harari Resolution, proposed by MK Yizhar Harari and adopted on June 13, 1950. It directed the Constitution, Law and Justice Committee to prepare a constitution in chapters, each enacted as a separate Basic Law, with the chapters ultimately to be consolidated into the constitution of the state.[12] The resolution was a Knesset decision rather than a statute and was characterized as declaratory. It did not settle whether each Basic Law would possess constitutional status immediately or only after consolidation, leaving a question that shaped later legal debate.[12][8]

Basic Law: The Knesset was enacted by the Third Knesset on February 12, 1958, and published in Sefer Ha-Chukkim No. 244 on February 20. The published text identifies David Ben-Gurion as prime minister and Yitzchak Ben-Zvi as president.[2] As the first Basic Law, it began the practical implementation of the chapter-by-chapter constitutional project.[3]

The law has been amended repeatedly as electoral and parliamentary questions have developed. An amendment passed on April 30, 2018, imposed a 14-year candidacy restriction, measured from the end of the sentence, on otherwise qualified citizens convicted of serious terrorism or security offenses and sentenced to more than seven years' actual imprisonment. It took effect on publication on May 2, 2018.[9]

A 2016 amendment created a procedure for terminating the membership of a sitting MK who, after election, engaged in incitement to racism or support for armed struggle against the state. The process requires initiation by 70 members, including at least 10 from opposition groups, committee approval by a three-fourths majority, and a final vote of 90 members; the decision may be appealed to the Supreme Court.[13]

The dissolution provisions also have practical constitutional consequences. In May 2019, after Prime Minister Benjamin Netanyahu's mandate to form a government expired, the Knesset dissolved itself, preventing President Reuven Rivlin from assigning the task to another Knesset member.[11]

Section 7A was added on July 31, 1985, during the Eleventh Knesset. Its enactment followed the 1984 election dispute in which the Central Elections Committee disqualified the Kach list led by Meir Kahane, the Supreme Court found no legal basis for the exclusion, and Kach subsequently won one seat.[2][14]

The original provision applied to candidates' lists and stated three separate grounds: negating Israel's existence as the state of the Jewish people, negating the democratic character of the state, and inciting racism.[2] It did not contain the current combined phrase "Jewish and democratic state," did not expressly cover individual candidates, and did not include support for armed struggle. Later amendments changed the wording, extended the section to individuals, and added support for armed struggle by an enemy state or terrorist organization against Israel.[15][5]

The Supreme Court has required clear, convincing, and unequivocal evidence before a list or candidate may be excluded.[5] In 2003, an eleven-justice panel unanimously overturned the disqualifications of Ahmed Tibi and Azmi Bishara because the evidence did not meet that threshold; the court also held that the statements and conduct cited against Tibi did not establish support for a terrorist organization's armed struggle.[5][5] In February 2015, the Court likewise declined to approve the disqualification of two candidates.[7]

An earlier precedent arose in 1965, when the Central Elections Committee disqualified the Arab Socialist List associated with the al-Ard movement and the Supreme Court upheld the decision. The case has been described as an application of "defensive democracy" before Section 7A existed.[16] Disputes have continued under the statutory framework, including the Central Elections Committee's 2022 decision to disqualify Balad, which was challenged in the Supreme Court.[17]

Israel has no single consolidated constitutional document. Its constitutional order developed through the gradual enactment of Basic Laws, other legislation, the Declaration of Independence, and judicial interpretation.[4][8] Basic Law: The Knesset was unusual among the early Basic Laws because Section 4's absolute-majority requirement suggested a rank above ordinary legislation and enabled courts to invalidate election-related statutes that violated an entrenched requirement without the necessary majority.[8]

The Supreme Court's 1995 United Mizrahi Bank decision recognized judicial review of ordinary legislation under the two Basic Laws enacted in 1992 concerning human rights. Sources have differed over how broadly that development elevated the Basic Laws as a whole, and the absence of a completed constitutional document has continued to generate disagreement over their precise normative rank.[8][18]

The question of judicial review of a Basic Law itself changed materially on January 1, 2024. In a 12–3 decision, the High Court held that it has authority to review Basic Laws in exceptional and extreme cases in which the Knesset exceeds its constituent authority; by 8–7, it invalidated the amendment to Basic Law: The Judiciary that had eliminated reasonableness review of government and ministerial decisions.[19] The ruling established the authority claimed by the majority, although its scope and legitimacy remain contested in the sharply divided opinions.[19]

Analyses published by the Jerusalem Center for Public Affairs connect Israel's proportional system and multiparty politics to traditions of bargaining, proportionality, and group representation that developed in Zionist institutions and the Yishuv. One such analysis argues that Section 4's entrenchment reinforced this structure by preventing proportionality from being changed by an ordinary majority of those voting.[20][21]

As Israel's first Basic Law, Basic Law: The Knesset translated the Harari Resolution's chapter-by-chapter plan into a legislative instrument and supplied a durable framework for representative government.[3][8] Its definition of the Knesset, 120-member composition, electoral formula, terms, committees, public sittings, immunity, and continuity provisions still form the institutional foundation of parliamentary life.[2][2]

Section 4's six-part electoral formula remains central to Knesset elections, while its entrenchment produced some of Israel's earliest judicial enforcement of a Basic Law against ordinary legislation.[2][8] The term-extension and dissolution rules have also structured exceptional transitions, including the war-related postponement in 1973 and the self-dissolution of the Knesset in 2019.[10][11]

Section 7A added a statutory mechanism of defensive democracy, but the Supreme Court's demanding evidentiary standard limits its application in order to protect the right to elect and be elected.[5] The provision consequently remains a recurring arena in which electoral participation, Israel's character as a Jewish and democratic state, and protection against racism and support for terrorist armed struggle are weighed against one another.

Section 7A has generated disputes over both wording and application. The original 1985 provision referred separately to Israel as the state of the Jewish people and to the state's democratic character, applied only to lists, and omitted the armed-struggle ground.[2] Later versions use the combined formulation "Jewish and democratic state," cover individual candidates, and include support for armed struggle by an enemy state or terrorist organization.[15][5] Quotations of the provision must therefore be identified as historical or current rather than treated as interchangeable.

The constitutional rank of the Basic Laws also remains debated. The Harari Resolution did not specify when constitutional status would attach, and interpretations of the 1995 Mizrahi ruling differed over whether all Basic Laws or principally the two 1992 rights laws held superior normative status.[8][18] The January 1, 2024 ruling established a majority holding that the High Court may review and, in exceptional circumstances, invalidate a Basic Law, but the narrow 8–7 result on invalidation demonstrates continuing disagreement over the doctrine's application.[19]

Section 7A cases likewise expose a persistent tension between political participation and defensive democracy. The Central Elections Committee has repeatedly sought to exclude candidates or lists, while the Supreme Court has frequently required stronger proof and restored eligibility.[5][7] The law supplies legal grounds for exclusion, but their application remains politically and judicially contested.
