GMULAW is right. I mean you can say, "Your honor, if I may be heard," and argue with him/her but in your scenario the judge stated legal authority as the source for the ruling, which indicates that jugde has made up his/her mind as to the law, and you are not likly to change that opinion. Unless you have an alternative argument to make I'd say thank you your honor and sit down. Pissing off the judge is a surefire way to loose. Prepare you case with the expectation that any ruling could go any way and make sure to preserve your objections and offers of proof for appeal.
