Pro hac vice means a specific decision does not constitute a precedent because the decision is for the specific case only, not to be followed in other cases. A pro hac vice decision violates statutory law - Article 8 of the Civil Code - which states that "judicial decisions applying or interpreting the laws or the Constitution shall form part of the legal system of the Philippines."

Pro hac vice means a specific decision does not constitute a precedent because the decision is for the specific case only, not to be followed in other cases. A pro hac vice decision violates statutory law - Article 8 of the Civil Code - which states that "judicial decisions applying or interpreting the laws or the Constitution shall form part of the legal system of the Philippines." The decision of the Court in this case cannot be pro hac vice because by mandate of the law every decision of the Court forms part of the legal system of the Philippines. If another case comes up with the same facts as the present case, that case must be decided in the same way as this case to comply with the constitutional mandate of equal protection of the law. Thus, a pro hac vice decision also violates the equal protection clause of the Constitution.

It is the policy of the courts not to interfere with the discretionary executive acts of the executive branch unless there is a clear showing of grave abuse of discretion amounting to lack or excess of jurisdiction. Mandamus does not lie against the legislative and executive branches or their members acting in the exercise of their official discretionary functions. This emanates from the respect accorded by the judiciary to said branches as co-equal entities under the principle of separation of powers.
