The local Court of Appeals declined the case filed by ABS-CBN Corporation against GMA Network Inc. for allegations of illegal duplication of its live video footage.

[73] During a Senate hearing on the same day, public services panel chair Grace Poe stated they were to investigate ABS-CBN's compliance with the terms and conditions of its franchise.
