Short answer. The Supreme Court may dismiss the appeal motu proprio or on the respondent's motion for reasons including a late appeal, a petition lacking merit, unpaid docket fees, defective proof of service or missing required documents, disregard of a court circular without justification, the wrong mode or choice of appeal, or the case simply not being appealable to it.
What the law says
The appeal may be dismissed motu proprio or on motion of the respondent on the following grounds: (a) Failure to take the appeal within the reglementary period; (b) Lack of merit in the petition; (c) Failure to pay the requisite docket fee and other lawful fees or to make a deposit for costs; (d) Failure to comply with the requirements regarding proof of service and contents of and the documents which should accompany the petition; (e) Failure to comply with any circular, directive or order of the Supreme Court without justifiable cause; (f) Error in the choice or mode of appeal; and (g) The fact that the case is not appealable to the Supreme Court.

The court can act without waiting for a motion
Rule 56, Section 5 gives the Supreme Court authority to dismiss an appeal motu proprio — on its own initiative — or on motion of the respondent. This means procedural defects do not necessarily need to be raised by the other side; the court itself can catch and act on them, so an appellant cannot assume that silence from the respondent on a defect means the appeal is safe from dismissal on that ground.
Procedural and formal defects
Several grounds are procedural in nature: missing the reglementary period to appeal, failing to pay the required docket fee or make a cost deposit, failing to comply with proof-of-service requirements or the documents that must accompany the petition, and disregarding a Supreme Court circular, directive, or order without justifiable cause. These grounds focus on whether the appeal was properly and timely brought, independent of its substantive merits.
Substantive and jurisdictional grounds
Other grounds go deeper: lack of merit in the petition itself, error in the choice or mode of appeal, and the fact that the case is simply not appealable to the Supreme Court at all. These last two connect directly to the earlier requirement that an appeal be taken only through a petition for review on certiorari — choosing the wrong vehicle, or trying to appeal something the Supreme Court has no jurisdiction to review, exposes the appeal to dismissal on this list.
Why the list mixes procedure and substance
Grouping timeliness, fee payment, and documentation lapses alongside lack of merit and wrong mode of appeal in a single dismissal provision reflects that the Supreme Court, as a court of last resort with a heavy caseload, needs efficient tools to screen out appeals that either were not properly brought or plainly do not warrant its limited review capacity, without having to fully brief and argue every deficient petition to conclusion first.
