Interpleader requires conflicting claims upon the same subject matter are or may be made against the stakeholder who claims no interest whatsoever in the subject matter or an interest which in whole or in part is not disputed by the claimants
Through interpleader, the stakeholder can join all competing claimants in a single proceeding to determine conflicting claims without exposing the stakeholder to the possibility of having to pay more than once on a single liability
A successful litigant who has secured a final judgment in its favor cannot later be impleaded by its defeated adversary in an interpleader suit and compelled to prove its claim anew against other adverse claimants as that would in effect be a collateral attack upon the judgment
A petition for declaratory relief is no longer proper when the law, ordinance, or issuance has already been enforced and the penalty for its violation imposed against the petitioner
When the remedy of appeal is available to a litigant, a petition for certiorari shall not be entertained and should be dismissed for being an improper remedy
In certain instances, declaratory relief is proper should there be a question of the constitutionality of a statute, executive order or regulation, ordinance, or any other governmental regulation
Petitions for prohibition are filed to address the jurisdictional excesses of officers or bodies exercising judicial, quasi-judicial, or ministerial functions
There is an abysmal dearth of facts to sustain a finding of an actual case or controversy and the existence of a direct injury to petitioner, a petition for declaratory relief resolved after full-blown trial in a trial court would have been the more appropriate remedy
The Rules of Court provides two remedies to correct grave abuse of discretion: first, a special civil action for certiorari; and second, for prohibition
While certiorari and prohibition, as contemplated within the Rules of Court, were traditionally used to question only judicial and quasi-judicial functions, this Court has decided on such petitions despite them involving legislative and executive acts
A petition for mandamus will issue only when it is proven that petitioner has a clear legal right to the performance of the act sought to be compelled and the respondent has an imperative duty to perform the same
It is the petitioner who bears the burden to show that there is such a clear legal right to the performance of the act, and a corresponding compelling duty on the part of the respondent to perform the act
PSA has the ministerial duty of issuing certified transcripts or copies of any certificate or document registered upon payment of proper fees as mandated by Section 12 of Act No. 3753 or the Law on Registry of Civil Status
(when applied to public functionaries) a power or right conferred upon them by law or acting officially, under certain circumstances, uncontrolled by the judgment or conscience of others
An act or duty which an officer or tribunal performs in a given state of facts, in a prescribed manner, in obedience to the mandate of a legal authority, without regard to or the exercise of his own judgment upon the propriety or impropriety of the act done
If the remedy of appeal was previously available to the party, his/her Rule 65 petition will not prosper even if the ground therefor is grave abuse of discretion
Appeal and not a special civil action for certiorari was the correct remedy to challenge the dismissal of the second petition on the ground of res judicata
If there is no appeal or other plain, speedy, and adequate remedy in the ordinary course of law, a special civil action for certiorari may be availed of
The 60-day period to file a petition for certiorari is non-extendible to avoid any unreasonable delay that would violate the constitutional rights of parties to a speedy disposition of their case
The private respondent in a Rule 65 petition is mandated to appear and defend both on his or her own behalf and on behalf of the public respondent affected by the proceedings
