Legal Question in Constitutional Law in California

It really depends upon the context. In the sense of ordinary English usage, an overt act is one that is "Open and observable; not hidden, concealed, or secret," whereas a predicate act is one that is the base or foundation for something else. Those basic definitions don't really have much in common. In the criminal law context, especially as it relates to conspiracy, an open and observable (overt) act in furtherance of the conspiracy, may be a necessary foundation (predicate) for charging the actor as a co-conspirator. That is just general stuff. You really need to provide more context for your question.

I provide information about the law designed to help people safely

manage their own legal needs. But legal information is not the same as

legal advice -- the application of law to an individual's specific

circumstances. I do not know all the facts of your case, and do not

represent you. Although I strive to make sure the information I

provide is accurate and useful, I recommend you consult a lawyer who

can learn the details of your case more completely, to insure that the

information I provide, and your interpretation of it, is appropriate

to your particular situation.
