James Scott Cumberland Reid, Baron Reid, CH, PC, FRSE (30 July 1890 – 29 March 1975) was a Scottish Unionist politician and judge. His reputation is as one of the most outstanding judges of the 20th century.^[1]

He was born on 30 July 1890 in Drem, East Lothian the son of James Reid a Solicitor of the Supreme Courts (SSC) and his wife, Kate Scott. ^[2] Educated at Edinburgh Academy, he then studied law at Jesus College, Cambridge, graduating BA in 1910 and LLB in 1911. He was admitted as an advocate in 1914.

He was commissioned into the 8th battalion Royal Scots in World War I and was seconded to the Machine Gun Corps in 1916, serving in Mesopotamia and reaching the rank of Major. He resigned his commission in 1921. He was appointed a King's Counsel in 1932.

He was Member of Parliament (MP) for Stirling and Falkirk from October 1931 until his defeat in November 1935, and for Glasgow Hillhead from June 1937 until September 1948.

He served as Solicitor General for Scotland from June 1936^[3] until June 1941, and as Lord Advocate from June 1941^[4] until July 1945, and was appointed a Privy Counsellor in 1941.

In Shaw v DPP, (1961) UKHL 1 rendered on 4 May 1961, Reid said,

I shall not examine the authorities because I think that they establish that it is an indictable offence to say or do or exhibit anything in public which outrages public decency, whether or not it also tends to corrupt and deprave those who see or hear it. In my view it is open to a jury to hold that a public invitation to indulge in sexual perversion does so outrage public decency as to be a punishable offence. If the jury in this case had been properly directed they might well have found the accused guilty for this reason. And the offence would be the same whether the invitation was made by an individual or by several people acting in concert. But it appears to me to be impossible to say the same with regard to ordinary prostitution. The common law has never treated the appearance of a prostitute in public as an indictable offence however obvious her purpose might be, and an Act of Parliament has been found necessary to stop the nuisance of prostitutes parading in the public street.

In the same case, he went on to say:

Even if there is still a vestigial power of this kind it ought not, in my view, to be used unless there appears to be general agreement that the offence to which it is applied ought to be criminal if committed by an individual. Notoriously there are wide differences of opinion today as to how far the law ought to punish immoral acts which are not done in the face of the public. Some think that the law already goes too far, some that it does not go far enough. Parliament is the proper place, and I am firmly of opinion the only proper place, to settle that. When there is sufficient support from public opinion, Parliament does not hesitate to intervene. Where Parliament fears to tread it is not for the courts to rush in.
