is one piece episode 274 filler?

Spandam gets an update from the Marines. They've managed to locate Luffy atop the Courthouse.

This confuses Spandam since he knows Blueno was up there, too. He looks out his window again and sees Luffy recuperating by eating the meat he'd kept in his pockets.

Then he sees Blueno motionless nearby. Spandam can only make one sickening conclusion from this.

Luffy had defeated Blueno, a member of CP9, one of the most merciless organizations in the World Government. Such a feat should be unthinkable, but Luffy's defiant call for Nico Robin leaves no doubt who won that fight.
