On July 2, 1968, respondent Rice was arrested for driving while intoxicated on a North Carolina state highway. He was tried in the General County Court of Buncombe County, convicted, and sentenced to imprisonment for nine months with sentence suspended upon payment of $100 fine and costs. On appeal he was tried
de novo
in the Superior Court, found guilty, and sentenced to two years’ imprisonment. State post-conviction procedures were unavailing. On appeal from denial of federal habeas corpus, the Court of Appeals for the Fourth Circuit held that under
North Carolina
v.
Pearce,
The State claims that
Pearce
does not apply to a situation where the more severe sentence is imposed after a trial
de novo
in its Superior Court. We do not reach that question, however, since the threshold issue of moot
*246
ness was improperly disposed of by the Court of Appeals. Although neither party has urged that this case is moot, resolution of the question is essential if federal courts are to function within their constitutional sphere of authority. Early in its history, this Court held that it had no power to issue advisory opinions,
Hayburn’s Case,
*247
The Court of Appeals held that the case was not moot because it assumed that
Pearce
mandated expunction of Rice’s conviction and because the conviction, unex-punged, would have collateral consequences entitling Rice to challenge it. A number of disabilities may attach to a convicted defendant even after he has left prison,
1
and the Court has recognized the standing of such persons to challenge the legality of their convictions even when their sentences have been served.

It could not be clearer, however, that
Pearce
does not invalidate the conviction that resulted from Rice’s second trial;
Pearce
went no further than to affirm the judgment of a federal court ordering Pearce’s release “[u]pon the failure of the state court to
resentence
Pearce within 60 days . . . .”
Respondent’s sole claim under Pearce thus related to the sentence he had completely served when he came before the Court of Appeals. A different question of mootness is therefore presented than the Court of Appeals considered. Nullification of a conviction may have important benefits for a defendant, as outlined above, but urging in a habeas corpus proceeding the correction of a sentence already served is another matter. Respondent was first sentenced to nine months, suspended upon payment of a $100 fine; after trial de novo he was sentenced to two years. In some jurisdictions, if a defendant is adjudicated guilty, either by conviction or plea, and then is placed on probation, not sentenced, or given a suspended sentence, statutes imposing disabilities for criminal convictions have no application. 3 Elsewhere, however, the sentencing that follows adjudication of guilt is irrelevant for purposes of disability statutes. 4 Since the present record deals with the mootness question only from the standpoint of conviction vel non and is otherwise unilluminating as to whether there may be benefits to respondent under North Carolina law in having his sentence reduced after he has served that sentence, it would be inappropriate for us to deal with this issue as it has now emerged. Accordingly, we vacate the judgment of the Court of Appeals and remand the case to that court for reconsideration of the question of mootness.
7 So ordered.
