Since 1992, much of his judicial work was focused on advancing and shaping Israel's Constitutional Revolution (a phrase which he coined), which he believed was brought about by the adoption of Basic Laws in the Israeli Knesset dealing with human rights. According to Barak's approach, which was adopted by the Supreme Court, the Constitutional Revolution brought values such as the Right to Equality, Freedom of Employment and Freedom of Speech to a position of normative supremacy, and thereby granted the courts (not just the Supreme Court) the ability to strike down legislation which is inconsistent with the rights embodied in the Basic Laws. Consequently, Barak held that the State of Israel has been transformed from a parliamentary democracy to a constitutional parliamentary democracy, in that its Basic Laws were to be interpreted as its constitution.
