Whether a court of equity has authority to order entry and a survey of a privately owned cave to determine whether it extends beneath an adjoining landowner’s property.
Holding
Yes. A court of equity has inherent authority to order a limited inspection when a party shows a bona fide claim, a reasonable basis to suspect an underground trespass, and a genuine need for evidence that ordinary methods cannot adequately supply.
Reasoning
The court began with the ordinary rule that, absent a severance of estates, ownership of the surface includes ownership above and below the land. Thus, if Edwards’s cave extended beneath Lee’s land, Edwards’s underground use could constitute a trespass upon Lee’s property. Although cave-rights litigation was unusual, the court regarded caves and mines as materially alike for purposes of an inspection necessary to determine whether one owner’s underground works had crossed a boundary.
Equity’s inspection power was well established in mining disputes. A court may require a mine owner to permit inspection where an adjoining owner has reasonable grounds to suspect that minerals are being extracted from beneath the adjoining land. That same principle permits a survey of Edwards’s cave when the purpose is to learn whether the cave itself extends under Lee’s surface estate.
The necessary safeguards were present. Lee asserted a bona fide claim, identified a factual need for the survey, and Edwards had notice and an opportunity to oppose the request. The circuit court had surface surveys and conflicting expert opinions before it, but it reasonably concluded that those materials could not settle the issue as accurately as an actual survey of the cave.
