Israel What might be possible reasons for legal changes to the Israeli Supreme Court?

[Robert]

In response to the discussion between robrecht and Linde, in Constitutional Law, there are two types of constitutions a country may have: 

1) A written constitution, for example that of the United States of America.

2) An unwritten constitution (also termed "uncodified"), for example that of the United Kingdom.
Israel is a further example of this type of constitution.

Is the constitution of the United Kingdom written down?

It is often noted that the UK does not have a ‘written’ or ‘codified’ constitution. It is true that most countries have a document with special legal status that contains some of the key features of their constitution. This text is usually upheld by the courts and cannot be changed except through an especially demanding process. The UK, however, does not possess a single constitutional document of this nature. Nevertheless, it does have a constitution. The UK’s constitution is spread across a number of places. This dispersal can make it more difficult to identify and understand. It is found in places including some specific Acts of Parliament; particular understandings of how the system should operate (known as constitutional conventions); and various decisions made by judges that help determine how the system works.

An uncodified constitution is a type of constitution where the fundamental rules often take the form of customs, usage, precedent and a variety of statutes and legal instruments.[1] An understanding of the constitution is obtained through reading commentary by the judiciary, government committees or legal experts. In such a constitutional system, all these elements may be (or may not be) recognized by courts, legislators and the bureaucracy as binding upon government and limiting its powers. Such a framework is sometimes imprecisely called an "unwritten constitution"; however, all the elements of an uncodified constitution are typically written down in a variety of official documents, though not codified in a single document.
