Career
Granted by Edward III a monopoly of the sale of sweet wines in London in 1373 he was impeached for taking on each pipe a levy of 3s.4d. (16p) for himself as well as 10s. (50p) for the Exchequer.
The impeachment arose partly from a dispute between rival merchants and partly from an attack by the House of Commons on the policies of the Court.
In August 1376 Pecche lost his rank as an alderman and his freedom of the City. Pecche was a feudal tenant of John of Gaunt and also had business dealings with him and Gaunt"s influence gained John Pecche a royal pardon together with Parliament"s reversal of the judgment in January 1377.
However he was not taken back into favour by the Civic authorities.
