They can come from members of the public, another minister or an MP. What happens is that people write to me and say, “Here is the following situation: We think there is a conflict of interest and you should investigate.” We get quite a few of those. We look at them, and we try to apply the test set out in the act. Is there any evidence, or is there anything that could reasonably amount to a conflict of interest? If so, and if we decide we can investigate, we investigate.
First of all, we write to the person and say, “These allegations have been made. Can I have your opinion?” We get a response from the person. On that basis, we decide whether the response is good enough. If we decide that it doesn't satisfy us—if there is still a reasonable doubt that something is amiss—we have the ability to start an inquiry. We have the full power of the court to ask the person to come and satisfy us under oath, and they produce documents, etc. Then we issue a report.
