@rappler: Puno's position: If conviction threshold is fixed at 16 votes, Constitution should have explicitly said so WATCH: Former chief justice Reynato Puno vouches for a contextual interpretation of the Constitution, saying it will enable senators to consider whether colleagues who are legally incapacitated should be allowed to vote. Puno argues that if the intent of the Constitution is to keep the conviction threshold at 16, it should have explicitly said so. "By using two-thirds, the number of votes to convict will have to move depending on certain factors."
