I want to know the answer to the following question:
What institution has prosecuted groups that practice outside the official Church without permission?
All the background I'm provided with is that "The act of using Church of Scientology techniques in a form different than originally described by Hubbard is referred to within Scientology as "squirreling" and is said by Scientologists to be high treason.". Is that enough to answer the question?
Answer: no
