In United States v. Puig Valdes, --- F.4th ---, No. 23-3214 (9th Cir. 2025), on interlocutory appeal by the Government, the Court affirmed the district court’s ruling that the factual basis of a pre-indictment plea agreement signed by Yasiel Puig Valdes would be excluded at trial.
In July 2022, Defendant Yasiel Puig Valdes (“Puig”) signed a pre-indictment plea agreement with the Government, under which he would plead guilty to one count of making false statements to federal officers in violation of 18 U.S.C. § 1001, and in exchange, the Government would recommend a reduced sentence and decline to bring an additional charge of obstruction of justice under 18 U.S.C. § 1503. When Puig later declined to plead guilty, the Government declared that Puig was in breach of his plea agreement, and as a remedy it sought to enforce a provision of the agreement waiving all evidentiary objections to the admission of the plea agreement’s factual basis at trial. This waiver expressly included any objections based on Rule 410 of the Federal Rules of Evidence, which generally bars the admission, against a defendant, of any statements made during plea negotiations. The district court ultimately held that Rule 410 remained applicable here, and it therefore ruled that the factual basis of Puig’s plea agreement would be excluded at trial. Pursuant to 18 U.S.C. § 3731, the Government brought this interlocutory appeal challenging that pretrial ruling. Although our reasoning differs somewhat from the district court’s, we agree that Rule 410 remains applicable here, and we therefore affirm.On appeal, the Government contends that, even though the district court had not yet accepted either Puig’s plea agreement or any guilty plea from him, that agreement remained binding and enforceable, including its waiver of the rule of exclusion contained in Federal Rule of Evidence 410.[T]his written statement attributed to Puig plainly constitutes a “statement made during plea discussions with an attorney for the prosecuting authority,” and it is therefore “not admissible against the defendant who . . . participated in the plea discussions” where, as here, “the discussions did not result in a guilty plea.”However, because Evidence Rule 410 and Criminal Rule 11(f) were “enacted against a background presumption that legal rights generally, and evidentiary provisions specifically, are subject to waiver by voluntary agreement of the parties,” the Supreme Court has held that, “absent some affirmative indication that the agreement was entered into unknowingly or involuntarily, an agreement to waive the exclusionary provisions of [these] Rules is valid and enforceable.”Here, of course, the plea agreement was never accepted or approved by the district court before Puig disavowed it, and under this line of authority, the agreement would generally be deemed not to be enforceable by the court.Viewing the language of Puig’s plea agreement against the backdrop of this case law, we conclude that Puig’s Rule 410 waiver was not triggered here. As we have explained, Puig’s waiver of the protections of Rule 410 (and Rule 11(f)) was expressly contingent on the district “[c]ourt’s finding” that there was a “breach of this agreement.” The terms of that waiver are most naturally understood as requiring that there be an “agreement” that, under our case law, was enforceable by the “[c]ourt[]” and as to which the court could therefore make the requisite “finding” of a “breach.” And because the plea agreement was a Type A agreement requiring the district court’s approval, and because that approval never occurred, the agreement was not enforceable by the court under our precedent. The waiver, by its own terms, therefore did not apply. Consequently, Rule 410 remains applicable with full force here, and the factual basis of Puig’s plea agreement is “not admissible against” Puig.
