What is a difference between the texas constitution and the u. S. Constitution?

A difference between the Texas constitution and the U. S Constitution is that the Texas Constitution is supposed to provide a rigid structure for government, leaving no room for interpretation or whatsoever.

Whereas the US Constitution is what is known as a Case-law Constitution, that is, it is based on judicial interpretation of laws that have been enacted by legislative bodies and governing documents, where the document is meant only to provide a basic structure to the government.
