Respondent mishandled three cases and claimed she filed a brief by sliding it under the judge's door. Still referee lets her off with a reprimand and probation. Counsel for discipline agrees and seeks motion to approve with the Supreme Court. Supreme Court suspends attorney for one year with additional probation. The first private reprimand was dated December 18, 2000, and the second was dated October 30, 2003.... This court is seriously concerned with respondent's repeated neglect of matters entrusted to her. See State ex rel. Counsel for Dis. v. Sipple, 265 Neb. 890, 902, 660 N.W.2d 502, 512 (2003) (discussing attorney's prior private reprimands and stating that "we have held that cumulative acts of attorney misconduct are distinguishable from isolated incidents, therefore justifying more serious sanctions"). We further note that the record reflects respondent has received two prior private reprimands, one of which involved similar neglecting conduct, which we consider as aggravating factors in imposing discipline in this case. Upon due consideration of the record, the court finds that respondent should be and hereby is suspended from the practice of law for a period of 12 months, effective immediately.
