If Sereno never CJ, should all SC cases lost by 1 vote from 2012 be reversed, reviewed?
Maria Lourdes Aranal Sereno is a Filipino lawyer and judge who was the de facto 24th Chief Justice of the Supreme Court of the Philippines from 2012 until her ouster in 2018. Wikipedia She was thrown out of office through a highly-criticized quo warranto proceeding. Others say her ouster should have been through a more constitutional impeachment process.
An ouster through a petition for quo warranto means that the public officer has never been in office. In Sereno's case, the Supreme Court, in effect, declared that she was never the Chief Justice in the eyes of the law. All her acts as such officer have never been performed.
The legal consequence of this is that, if she was never legally there, should all cases decided from 2012 and lost by one (1) vote be reviewed and reversed?
It should be noted that, under the Rules of Court, a case before the Supreme Court which ends in a tie (meaning, the majority vote is not achieved) should be dismissed and the decision or order appealed from is considered affirmed. If the issue is constitutionality, the act's legality is upheld.
