WHERE do you get this notion? Is the Judicial Branch the only one that can READ? The Constitution was written to be understood by EVERYBODY. The Founders appear to have thought that Joe Sixpack was capable of rational, coherent thought, unlike politicians and lawyers of today, and could reasonably be expected to KNOW when the legislature and executive were in violation. The Supremes ASSUMED that power in 1803 or so, in Marbury v Madison, but it was NEVER assigned to them and ALL BRANCHES of the federal government were supposed to avoid doing UnConstitutional things. If you REALLY BELIEVE what you just wrote, your ignorance is appalling.
P.S. You might actually want to read Marbury v. Madison before you reply.
