Quoting a letter to the editor in Mishpacha:
One of the features of the “override clause” is that the legislature can override any ruling by the Israeli Supreme Court with a simple majority vote in the Knesset.
But what is so confusing to the American chareidi community is the introduction of this override clause. This is because introducing an equivalent of the “override clause” in the US judicial system would basically mean that popular opinion would override the law, and we would have nowhere to appeal rulings issued against our values when protected by the law.
…
Potential laws regulating bris milah, shechitah, the curriculum in chadarim and Bais Yaakovs, the definition of marriage and death, and when our yeshivos, camps, and shuls can be opened will not be drafted based on true science and medicine, but will be driven by the moment’s popular opinion. So the Supreme Court is the address for citizens and groups to appeal these new laws, and where the latest trends in popular opinion are held in check with the land’s Constitution.
