11. A filed against her estranged husband X a petition for custody of B before the Regional Trial Court (RTC)-Quezon City where X lived together with B. When X learned of the petition, he, together with B, moved to another residence in Iloilo City. When A found out what X did, she again filed a petition for custody of B before RTC-Iloilo City. When X learned of this second case, he once again changed residence, this time, in Zamboanga City. A then resorted to a petition for habeas corpus against X to produce the live person of B before the Court of Appeals. A alleged that X was illegally restraining B, and withholding from her custody over their child. Was A’s resort to habeas corpus before the Court of Appeals justified? Reason(s).
