This case presents the question whether an appellant’s failure to appeal one of two alternative grounds for a trial court’s decision waives any further appellate review of that decision. We hold that it does, subject to the caveat that the alternative holding must be legally capable — standing alone— of supporting the trial court’s decision.
*115 I.
The trial court found Otis Purcell Johnson, Jr., guilty of possession of heroin with intent to distribute. Before trial, Johnson moved to suppress the evidence on the ground that the arresting officer violated the Fourth Amendment by conducting an overbroad weapons frisk during an investigatory detention. During this frisk, the officer discovered heroin in a balled-up jacket that Johnson had been tightly clutching. At trial, the officer testified that outstanding warrants existed for Johnson’s arrest at the time of the encounter — a fact he would have learned moments later while checking Johnson’s identification. A search incident to arrest, the officer stated, would have necessarily followed.
The Commonwealth responded to the motion to suppress on two grounds. First, the prosecution claimed the circumstances justified a weapons search of the jacket.
See generally Simmons v. Commonwealth,
The trial court denied Johnson’s motion to suppress, holding that (i) the officer did not exceed the permissible limits of a weapons frisk, and (ii) in any event, the evidence proved the heroin would have been “inevitably discovered” by the officer even if the weapons frisk had not taken place due to the presence of several outstanding warrants for Johnson’s arrest at the time of the encounter. Relying on both grounds, the trial court denied the motion.
II.
On appeal, Johnson challenges only the trial court’s first holding. He argues the trial court erred in finding the *116 weapons frisk was within the scope of permissible Fourth Amendment limits. On that basis, Johnson requests that we reverse the trial court’s denial of the suppression motion and vacate his conviction. Johnson, however, does not challenge on appeal the trial court’s alternative holding applying the inevitable discovery doctrine to the facts of this case. 1
From a practical point of view, for us to reverse the judgment, we would have to raise a challenge on Johnson’s behalf to the trial court’s inevitable discovery ruling, conceive of a reason to find fault with it, and then use that reason as a basis for setting aside Johnson’s conviction. Suffice it to say, such an exercise of sua sponte judicial power would impermissibly place us in the role of advocate — far outside the boundaries of our traditional adjudicative duties.
For these reasons, we join the majority of jurisdictions holding that in “situations in which there is one or more alternative holdings on an issue,” the appellant’s “failure to address one of the holdings results in a waiver of any claim of error with respect to the court’s decision on that issue.”
United States v. Hatchett,
That said, we still must satisfy ourselves that the alternative holding is indeed one that (when properly applied to the facts of a given case) would legally constitute a freestanding basis in support of the trial court’s decision.
See, e.g., Navajo Nation v. MacDonald,
In this case, we agree with the trial court that the inevitable discovery doctrine, when properly applied, serves as an adequate and independent legal basis for denying Johnson’s motion to suppress.
See Jones,
For these reasons, we reject Johnson’s appellate challenge to the trial court’s denial of the motion to suppress and affirm his conviction.
Affirmed.
Notes
. In its appellee's brief, the Commonwealth raised the trial court’s inevitable discovery ruling as an alternative basis for affirming Johnson’s conviction. Johnson filed no reply brief, which he had a right to do under Rules 5A: 19(c)(3) and 5A:22.

. We reach this conclusion without first deciding the merits of the properly appealed question concerning the scope of the

weapons frisk. Given our holding, any discussion on that point would conflict with two principles of judicial self-restraint: our reluctance to issue what amounts to an "advisoiy opinion” on an inessential subject,
