## Facts

- Baltimore City owned and operated a municipal stadium originally built in 1922 and historically used for large public athletic and civic events.
- Stadium lights were installed in 1939, increasing the facility’s potential for night events.
- After the Baltimore Orioles’ home park burned in 1944, the city permitted the Orioles to use the municipal stadium; in 1947 the city and the Orioles entered a longer-term agreement for regular home games, including night games.
- Nearby homeowners alleged the intensified professional baseball schedule created recurring disturbances, including amplified sound from a public-address system, glare from floodlights into homes, heavy traffic and parking congestion, dust from unpaved parking areas, and disruptive fan behavior.
- The homeowners sought equitable relief to stop or materially limit professional baseball and related operations, and argued the arrangement was unlawful as (i) a private nuisance, (ii) beyond municipal authority, and (iii) an unlawful extension of a nonconforming use under zoning rules.
- The trial court declined to enjoin professional baseball at the stadium but imposed limited operational restrictions (including limits on certain loudspeaker uses and some internal facility uses); the homeowners appealed.

## Issues

1. Whether regular professional night baseball at a municipal stadium, with associated noise, lights, traffic, dust, and crowds, constituted a private nuisance warranting broad injunctive relief.
2. Whether Baltimore City lacked statutory or charter authority to allow professional baseball to use the municipal stadium under a long-term agreement.
3. Whether the increased and more frequent stadium use amounted to an unlawful extension or change of a nonconforming use under Baltimore’s zoning ordinance.
4. If some harms were shown, what scope of equitable relief was appropriate in light of competing private and public interests.

## Decision

- The Court of Appeals of Maryland affirmed the denial of a sweeping injunction against professional baseball and the Orioles’ general use of the stadium.
- The court held that the complained-of conditions, though annoying to residents, did not constitute a substantial and unreasonable interference requiring abatement of the stadium’s principal operations.
- The court rejected the claim that the city acted beyond its authority by permitting professional baseball and entering a revenue-producing agreement for stadium use.
- The court concluded that the change from occasional events to more frequent professional baseball was a change in degree within the stadium’s general athletic/recreational purpose, not a different use barred by zoning as an impermissible nonconforming-use extension.
- The court approved limited, targeted restrictions aimed at avoidable harms (including certain loudspeaker practices) rather than shutting down stadium operations.

## Legal Principles

- A lawful, publicly authorized recreational facility is not a nuisance per se; to justify injunctive abatement, the interference with neighboring property must be substantial and unreasonable in context.
- In assessing nuisance claims, courts consider the character of the locality and distinguish unavoidable incidents of the permitted activity from preventable or gratuitous aggravations.
- Zoning rules disfavor extension of nonconforming uses, but increased intensity of an established use may be treated as a difference in degree rather than a prohibited change in kind, particularly where the activity remains within the established purpose of the property.
- A municipality acts within its authority when it operates a stadium for athletic events and permits professional contests absent an express legal prohibition.
- Equity may grant tailored relief to mitigate specific, demonstrable harms while declining relief that would effectively close or cripple a significant public facility.

## Conclusion

The court refused to enjoin professional night baseball at Baltimore’s municipal stadium because the residents’ complaints did not meet the threshold for abating the stadium’s core operations, the city had authority to permit professional use, and zoning law did not treat the intensified schedule as a new prohibited use; limited operational limits were appropriate to reduce avoidable impacts.
