The U.S. Supreme Court case East Central Eureka Mining Company v. Central Eureka Mining Company in 1906 revolved around a dispute over mining rights and property boundaries between the two companies in California's gold country. The plaintiff, East Central Eureka Mining Co., claimed that it had the right to mine certain veins of ore which extended into the defendant’s (Central Eureka Mining Co.) territory under their common boundary line, based on an interpretation of federal mining laws from 1866 and 1872. However, the defendant argued they held exclusive rights to these veins as per state law provisions regarding vertical ownership of land extending indefinitely upwards and downwards from surface boundaries. The court ruled in favor of Central Eureka Mining Co., stating that while federal law did allow for extralateral rights - or the right to follow lodes or veins beyond one's vertical side lines when they dip into another person's claim - this only applied if those veins apexed (or came closest to earth’s surface) within their own property lines; otherwise, state laws respecting absolute ownership prevailed.

The dissenting opinion in the case of East Central Eureka Mining Company v. Central Eureka Mining Company argued that the majority had erred in their interpretation of property rights and mining law. The dissenting justices believed that a miner's right to extract minerals from beneath another person's land should be limited by reasonable use, not absolute ownership as suggested by the majority ruling. They contended that allowing one party unfettered access to resources under someone else’s land could lead to wasteful practices and unnecessary damage, which would contradict public policy objectives aimed at conserving natural resources for future generations. Furthermore, they disagreed with the majority's assertion that such unrestricted mineral extraction was consistent with established customs and laws governing mining operations.
