ISSUE:
Whether the presence of author-members in the committee violates the principle of impartiality and fairness?
Whether the doctrine of necessity applies to justify the participation of author-members in the selection process?
Whether the method of selecting books under administrative resolutions is fair and unbiased?
RULE:
The principle of nemo judex in causa sua (no one shall be a judge in their own cause) ensures that individuals with a vested interest in a matter should not participate in decisions where they have a personal stake, maintaining fairness and impartiality in judicial and decision-making processes.
The doctrine of necessity applies only if there is no alternative course of action available.
