Because objections are technically not motions. They could be combined with a motion (which would then be granted or denied), but otherwise, they are registering complaints and issues.
Also, you can't deny an objection -- the objection is there whether you like it or not -- but you can either agree or disagree with its validity. A judge's opinion ranks top in the pecking order of the courtroom, so his agreement or dissent actually either sustains or overrules an argument.
What if someone strenuously objects?
No offense to Amanda Rice, but that's like saying "why are TV shows 'renewed' or 'cancelled' instead of 'in print' or 'out of print'?" I don't know how else to say this except that a word has to describe what it's supposed to describe, and if it doesn't, it's not the right word.
`When I use a word,' Humpty Dumpty said in rather a scornful tone, `it means just what I choose it to mean -- neither more nor less.'`The question is,' said Alice, `whether you can make words mean so many different things.'`The question is,' said Humpty Dumpty, `which is to be master - - that's all.'
Seems I like everything today, which wouldn't be notable except that it's so unusual.
Okay, but I think that in this analogy, Amanda is Humpty.
I really only kind of like this. But I felt it needed someone to like it.
