  Where the Daubert standard ensures that any scientific evidence presented in a trial has been reviewed and tested by the relevant scientific community, a Daubert challenge is a motion to exclude all or part of expert testimony due to it failing to meet the Daubert standard.

Can you bring any additional research or opinion into this discussion?
