Yes, because just like a notary who witnesses a signature and can be called into court to testify about a signed document, so can a Justice of the Peace (JP) can be called too; especially if they witnessed an affidavit or statutory declaration, as they are authorized to verify signatures and oaths. The JP typically needs to be listed as a witness and issued a subpoena to compel their testimony, though their role is to attest to the signing, not the truth of the document's content, requiring proper court procedure like pre-trial disclosure.
