Dismissal of appeal for informalities; opportunity to cure

Whenever an appellant files an incomplete transcript, or files the transcript or a further application for an extension, within three judicial days after the return day, or omits to file as part of the record any transcript exhibits offered in evidence, or whenever because of any error on the part of the clerk of court or of the trial judge, or for any purely technical reason, a motion to dismiss his appeal is filed either by an appellee, third person or intervener, charging and setting forth as grounds for dismissal any of the above reasons, no appellate court shall maintain said motion to dismiss, or dismiss the appeal, unless it first allow to the appellant at least two additional days, exclusive of Sundays and holidays, to cure and correct any and all the informalities and irregularities alleged and complained of in the motion to dismiss. Such appellant, before the date on which the motion to dismiss is fixed for trial, may cure and correct any objection, irregularity or informality charged or alleged to exist in the motion to dismiss, and if it appears to the appellate court that he has done so, the motion to dismiss shall be denied.
