Mlle Johanna Wagner was engaged by
Benjamin Lumley to sing exclusively at
Her Majesty's Theatre on
Haymarket from 1 April 1852 for 3 months, two nights a week.
Frederick Gye, who ran
Covent Garden Theatre, offered her more money to break her contract with Mr Lumley and sing for him. Sir James Parker granted an injunction to restrain Mlle Wagner. She appealed. ==Judgment==
