"5.2 Subject to Clause 9.2 below the HDA is not required to [discharge his/her operational responsibilities] [its work in the business] personally and in the event that he/she does not want to do so for any reason (including holiday) or is unable to do so for any reason (including illness) the HDA will ensure that he/she engages suitable people to ensure that his/her obligations under this Agreement are fully complied with."
"In the event that the contractor is unable or unwilling to perform the services personally he shall arrange at his own expense entirely for another suitable person to perform the services" and by paragraph 13 of the Schedule to that Agreement: "
"(13) That right for Mr Tanton to provide a substitute driver was utilised by him from time to time and, exceptionally, throughout a period of six months whilst Mr Tanton was ill, Mr Tanton paying the substitute driver, though receiving remuneration from the appellant, Clause 3.3, as the chairman expressly found, is not a sham."

This has been affirmed in the more recent cases of Carmichael ( Carmichael -v- National Power Plc[2000] IRLR 43 ) and Montgomery ( Montgomery -v- Johnson Underwood Ltd[2001] IRLR 269 . There was a mutuality of obligation. Mr Potter had to provide his own work and skill in return for remuneration. However, he could substitute a third party in his place. We find that this was a limited right of substitution as the substitute had to meet with the respondent's approval and the respondent had previously provided their own substitute for the applicant.
