It is also basic that the power to issue a writ of injunction is to be exercised only where the reason and necessity therefor are clearly established, and only in cases reasonably free from doubt.
For, truly, a preliminary injunction should not determine the merits of a case, or decide controverted facts.
As a preventive remedy, injunction only seeks to prevent threatened wrong, further injury, and irreparable harm or injustice until the rights of the parties can be settled.
As an ancillary and preventive remedy, it may be resorted to by a party to protect or preserve his rights during the pendency of the principal action, and for no other purpose. Such relief will accordingly protect the ability of the court to render a meaningful decision; it will further serve to guard against a change of circumstances that will hamper or prevent the granting of proper relief after a trial on the merits. Verily, its essential function is to preserve the status quo between the parties until the merits of the case can be heard (BPI vs. Hontanosas Sr., G.R. No. 157163, June 25, 2014).
