I think you can, it seems to agree with much of what has been said:
Proceeding against the Receiver 62. It will not usually be appropriate to proceed against the receiver personally, though the terms of appointment may be so wide as to make the receiver a 'person in control' of premises for the purposes of s.4, HSWA. No proceedings against a receiver should be commenced without consulting the Legal Adviser's Office.
From that it seems that it depends on the terms of the appointment, so if the receiver takes over the entire running of the business then they may be responsible for ensuring staff training etc takes place, but if they are there simply to manage the financial affairs then the duty would still rest with the employer. If the receiver removes funding for such as H&S training / PPE then they are asserting control and I would say that elements of the person having control from both pieces of legislation would apply accordingly.
The public interest test is mentioned quite a lot, and I would assume that they are hinting that they would not bother wasting time prosecuting an employer who is in receivership due to the likelihood of just adding the debts or a minimal fine being issued, however if the receiver could be held accountable then the public interest test would not present much of a problem.
