Com. v. Adams, T., 327 A.3d 667

Tyler Thomas Adams was charged in two consolidated criminal cases in Northumberland County, Pennsylvania, involving charges like aggravated assault, carrying a firearm without a license, and conspiracy to commit robbery.
Criminal complaints were filed on October 30, 2020 (case 154), and January 14, 2021 (case 156).
Adams filed two motions to dismiss under Pa.R.Crim.P. 600 (prompt trial rule), arguing excessive pretrial delay; both motions were denied.
Adams pled guilty on December 4, 2023, to certain charges pursuant to a negotiated agreement, and was sentenced to 2 to 6 years’ incarceration concurrent to another sentence.
On appeal, Adams argued the trial court wrongfully denied his Rule 600 motions without a hearing and without proper evaluation of the Commonwealth’s due diligence.
The key legal point was whether Adams waived his Rule 600 claims by entering an unreserved guilty plea.

Issue	Adams's Argument	Commonwealth's Argument	Held
Did Adams waive his Rule 600 claim by pleading guilty?	He should be allowed to appeal denial of Rule 600.	Issue not preserved; waiver applies.	Waived: claim not reserved at plea/sentencing.
Did the court err by denying the Rule 600 dismissal without a hearing?	Rule 600 motion should not have been denied summarily.	Motion was properly denied.	Waived by guilty plea; not reached.
Did the Commonwealth fail to act with due diligence under Rule 600?	Commonwealth failed to bring case to trial promptly.	Prosecuted case with due diligence.	Waived by guilty plea; not reached.

Commonwealth v. Singleton, 169 A.3d 79 (Pa. Super. 2017) (Defendants may enter a plea conditioned on appellate review of specific issues if reservation is clear.)
Commonwealth v. Snook, 230 A.3d 438 (Pa. Super. 2020) (Plea agreements are construed under contract principles; ambiguity against the government.)
