Is there any case law where a defendant has not yet filed an answer on a motion to change venue?

Cholakian contends venue in Sacramento County was improper and transfer to San Mateo County was mandatory. He argues that because he had not yet filed an answer, the court's consideration of the opposition was premature. Cholakian relies on an encyclopedia entry: [W]here there are several proper and necessary defendants, all of them must have filed answers before the plaintiff's countermotion will be entertained.
