Upon what grounds may a court allow intrusion into privacy of communication and correspondence?
The Constitution is silent on this matter but since Section 3, like Section 2, guarantees the right of privacy, the requirement of Section 2 as to what constitutes probable cause may guide the court accordingly in issuing the said intrusion. In other words, the sound discretion of the court as to what is deemed justified in each case, considering the requirements of probable cause, would be a yardstick in determining whether or not the court has committed grave abuse of authority or discretion.
