Electrical General Corp. v. LaBonte, 454 Md. 113

Summary

The Maryland Court of Appeals held that a subsequent intervening event does not automatically bar an employer’s liability for additional workers’ compensation benefits when an employee’s medical condition worsens. Where permanent partial disability has been apportioned between a work-related injury or occupational disease and other conditions, the Workers’ Compensation Commission may award additional benefits for worsening attributable solely to the work-related injury or disease. Causation and apportionment are factual matters for the Commission to determine.

Holdings

1. When the Commission has awarded permanent partial disability benefits based on an accidental personal injury or occupational disease and has also found a subsequent intervening event, the employee may receive additional permanent partial disability benefits for any subsequent worsening caused by and reasonably attributable solely to the accidental personal injury or occupational disease.
2. The final-accident rule applies to temporary disability benefits, but it does not govern liability for permanent partial disability benefits, which may be apportioned among multiple causal injuries or conditions.
3. A subsequent intervening event does not, per se, preclude employer liability for additional medical treatment or medical expenses; the relevant factual question is whether the worsening condition was caused by the accidental personal injury or occupational disease and therefore necessitated the treatment or expenses.

Questions Presented

1. Whether a prior finding that an employee sustained a subsequent intervening event bars further employer liability for workers' compensation benefits attributable to a prior accidental personal injury.
2. Whether, after a workers' compensation claim involving permanent partial disability has been apportioned between a work injury and a subsequent intervening event, the Commission may award additional permanent partial disability benefits when the employee's condition worsens and the worsening is attributable solely to the work injury.
3. Whether the existence of a subsequent intervening event categorically precludes liability for additional medical treatment and medical expenses related to a worsening of the employee's condition.

Disposition

affirmed
