Key v. Muse, 352 S.W.3d 857

Muse filed a health care liability suit against Key on June 11, 2009 for alleged negligence during a April 2007 surgery.
Key was not served with citation until July 28, 2010; substituted service was sought in June 2010.
Muse served an expert report by Dr. James Butler on October 5, 2009, within 120 days of filing, with a Certificate of Service claiming delivery to Key.
Key denied receiving Butler's report in 2009 or before his answer on August 12, 2010.
Muse later provided Key's attorney a copy of Butler's report on September 3, 2010.
The trial court denied Key’s motion to dismiss on September 22, 2010; Key appealed under an accelerated interlocutory procedure.

Issue	Plaintiff's Argument	Defendant's Argument	Held
When is a defendant a “party” for § 74.351(a) timing?	Muse contends Key becomes a party upon service or appearance, triggering § 74.351(a) obligations.	Key argues a party is one served or appearing; Muse did not serve Key within 120 days, so dismissal was required.	The term ‘party’ means a defendant who has been served, accepted/waived service, or appeared.
Was Muse’s expert report timely served on a party?	Muse served Butler's report within 120 days of filing.	Key was not a party within 120 days due to lack of service; report timely service did not occur.	Muse failed to serve on a party within 120 days; trial court abused discretion by denying dismissal.
Should the court create a diligence or open-courts exception to the 120-day deadline?	Equitable relief due to defendant’s evasion should toll the deadline.	Statute requires strict compliance; no judicially engrafted exceptions.	No diligence or open-courts exception; 120-day deadline is strict and not tolled by equity.
Does the agency’s obligation to object to the report affect jurisdictional issues?	Defendant’s obligation to file objections might affect jurisdiction.	Objections must be timely after service; before service, objections would waive jurisdiction.	Not addressed as issue since the 120-day issue governs and favors dismissal.
