Why make locums responsible for governance in revalidation?

How much more do you expect practices employing a locum for a day or single session to do as a routine?"The very least an individual locum can do is to ask every practice to sign a declaration - why not put it at the end of your invoice? – stating that they will inform you within a set time of any feedback, incidents, changes to your management, mistakes or compliments that they receive about you"
(DOI partner in a practice trying to only use locums in dire emergencies - so not in regular contact: would be different if, as it were, on a "Bank" pool system).
"But the idea that part of a locum's appraisal will be based on the clinical governance of an organisation over whom they have no say or control seems obtuse."
