Facts
The Earl of Northumberland in 1568 was Thomas Percy, 7th Earl of Northumberland. The Queen was Elizabeth I of England. Some copper miners in Keswick found an admixture of gold in copper mined from lands belonging to the Earl of Northumberland. Due to concerns about revenue and the possibility of a renewed war with Spain, the Queen’s advisers were anxious to claim prerogative rights to the gold. A suit was brought in the Court of Exchequer Chamber and judgment was for the Queen founding the Crown’s right to mine gold or silver. The challenge by the Earl of Northumberland was on the ground that the work was within the Royalties granted to his family in a former reign.Judgment
Twelve judges decided in favour of the Queen, The neglect of the Earl and his predecessors to work the minerals during seventy years 'had made that questionable which for ages was out of question', and the prerogative was revoked. This illustrates that in theory all gold and silver belongs to the queen, and that most authorities to extract minerals granted have a "use it, or lose it" component.Significance
On 28 May 1568 two mining monopolies were created, the Company of Mineral and Battery Works and the Society of Mines Royal. The effects of the decision were limited by the Mines Royal Act 1690, which removed the monopoly of these two companies.Reporting of the case
One report featured in the later English Reports series. Plowden’s extensive report was published some years after the judgment.Subsequent cases
The case has remained the leading case in New Zealand law on the royal prerogative to the royal metals of gold and silver; by statute all related royalties flow to the government of New Zealand. The case was also the authority on which the controversial Miner's Licences in Australia were introduced at the time of theNotes
