How did anyone every think these medical gag contracts were legal?

In the form, medical professionals promise not to violate federal law as long as you don’t say mean things about them. Go ahead and break the law and see what the government thinks of your excuse “but she said mean things”.

These forms are often signed under duress- the patient needs medical care. With a decent lawyer, that invalidates most contracts.

And hello, Hippocratic Oath. I don’t know if dentists take it, but if an MD refuses to treat because someone doesn’t sign this contract- that violates professional ethics.
