In 1995, Aharon Barak, President of the Supreme Court of Israel (1995-2006), decreed that “everything is justiciable,” everything can be done by judges; enabling the Supreme Court to carry out a judicial coup d’état.

Isn't that what Marbury v. Madison (1803) decreed?

And isn't it the job of courts to put a restraint on direct democracy?

Is that what this author wants? A direct democracy?

Yes, courts can become corrupt. But our own Supreme Court was mostly respectful of the Constitution until about 1930s, when they buckled under FDR's threat to pack the court. The court has been downhill from there.

Marbury is in the USA, which is a very dissimilar system, with three distinct branches of government.

Israel is a parliamentarian system, where the branches are far less distinct
