Scott graduated as doctor of civil law, and, after a customary year of silence, commenced practice in the
ecclesiastical courts. His professional success was rapid. In 1783 he became registrar of the court of faculties, and in 1788 judge of the consistory court and advocate-general, in that year too receiving the honour of
knighthood; and in 1798 he was made judge of the
high court of admiralty. In this capacity he heard on appeal two important cases having to do with the abolition of the slave trade. On 22 May 1809 took
Donna Marianna on the Cape Coast for breach of the
Act for the abolition of the slave trade. The
Vice admiralty court at Sierra Leone condemned the vessel. Although
Donna Marianna was ostensibly a Portuguese vessel, Scott upheld the seizure on the grounds that she was actually a British vessel and her Portuguese papers were a fraud. The second case involved the French ship
Le Louis (1816) after it had been seized by the
West Africa Squadron for slave trading off the African coast at
Cape Mesurado.
HMS Queen Charlotte had originally vindicated the seizure and confiscation of the ship and cargo. However Scott overturned this judgement, saying that the way
Le Lois had been stopped and boarded was illegal as "No nation can exercise a right of visitation and search on the common and unappropriated parts of the sea, save only on the belligerent claim." He accepted that this would constitute a serious impediment to the suppression of the slave trade, but argued that this should be remedied through international treaties rather than Naval officers exceeding what they were permitted to do. He twice contested
Oxford University in 1780 without success, but successfully in 1801. He also sat for
Downton in 1790. He was elected a
Fellow of the Royal Society in 1793. Upon the coronation of
George IV in 1821 he was raised to the peerage as
Baron Stowell, of
Stowell Park in the County of Gloucester, taking his title from the name of his estate. After a life of judicial service Lord Stowell retired from the bench – from the consistory court in August 1821, and from the high court of admiralty in December 1827. ==Personal life==
