Supreme Court upheld presidential election protest due to pre-voting marks on voter list affecting results.

The Supreme Court upheld a protest against the presidential election results, finding a violation of electoral law. The petitioner alleged that marks indicating card collection were placed on her and her husband's names before they arrived at the polling station, while a similar mark for her mother-in-law was placed after she was already registered. The court accepted witness testimony that these premature marks indicated unauthorized voters had cast ballots, concluding this irregularity could have influenced the election outcome.
