In 2008, Harvey, an experienced businessman, guaranteed a debt owed to Dunbar Assets plc (Dunbar).  Dunbar subsequently served a statutory demand on Harvey in 2011 for payment under the guarantee.

In 2012, Harvey applied, unsuccessfully, to set aside the demand in the County Court on the ground of promissory estoppel.  However, the demand was subsequently set aside by the Court of Appeal on a completely unrelated ground.
