Employees' Retirement System v. Dorsey, 59 A.3d 990

Respondent Sylvester Dorsey, a Baltimore City school police officer, was injured performing his duties on August 31, 2007.
Following termination of employment, ERS denied his application for line-of-duty disability retirement after a hearing examiner found impairments due to the incident and preexisting conditions.
Medical evidence showed 25% impairment to the back and 25% impairment to the right arm from the August 2007 incident, plus 15% back impairment attributable to preexisting degenerative disc disease.
The hearing examiner concluded the back impairment was not independent of the preexisting condition and denied benefits.
Circuit Court reversed the hearing examiner, and the Court of Special Appeals affirmed in part, prompting certiorari to address the independence requirement under § 9(j).
The Court held that a preexisting condition does not preclude eligibility so long as 50% total impairment (or 25% to two impairments) is directly attributable to the line-of-duty injury and independent of preexisting conditions.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Independence of preexisting condition in eligibility	Dorsey argues independence requirement is satisfied if 50% total impairment is direct result of line-of-duty injury.	ERS argues any causation by preexisting condition disqualifies eligibility though injury accounts for total impairment.	Preexisting condition does not bar eligibility; injury-based impairments can meet § 9(j) independently.
Calculation of impairment with preexisting condition	Respondent contends 25% back + 25% arm due to line-of-duty injury suffice, regardless of preexisting degeneration.	ERS contends impairment must be independent of preexisting condition for the calculation and may be reduced by preexisting factors.	Respondent satisfied the statutory thresholds; preexisting impairment may exist but does not alter the direct-line impairment required.
