What is the evidentiary test for exclusionary rulings under the deferential abuse of discretion standard?

We review a trial court's evidentiary rulings under the deferential abuse of discretion standard. (Miyamoto v. Department of Motor Vehicles (2009) 176 Cal.App.4th 1210, 1218.) Mother challenges the exclusion of her new evidence at the August 20, 2014 hearing. She claims that the basis for the exclusionary rulingthat she did not provide advance notice of the new evidence through a supplemental declarationdoes not withstand scrutiny because her supplemental declaration would have been stricken as improper rebuttal or impeachment testimony.
