The motion court clearly abused its discretion in striking plaintiffs affidavit in opposition to defendant Crisafi's motion to confirm the Referee's report, and confirming the report without considering it on the merits. While the court, in support of the challenged disposition, cited "gross violations" of court rules by plaintiffs counsel, the violations were technical, involving the length of an affidavit and the use of exhibit tabs, and did not rise to a level warranting the striking of the affidavit and consequent grant of the relief sought by Crisafi. While courts have inherent power to control their calendars and the disposition of business before them, deeming the violations of plaintiffs counsel "gross" was unwarranted and the sanction imposed by the court unjustifiably denied plaintiff her day in court ( see Matter of Hochberg v Davis, 171 AD2d 192).
