For the purpose of reaching a decision about potentially defective administrative action into which he is conducting an investigation, the Ombudsman may wish to compel people to engage in various sorts of testimonial activity—the furnishing of information in writing, the production of documents, the answering of questions orally. This article examines the Ombudsman’s powers in that regard, pointing to matters which may give rise to difficulties in the exercise of such powers and suggesting a number of changes to the relevant provisions. Some of the matters discussed are relevant to the information-gathering powers of other Commonwealth agencies, for example, the Taxation Commissioner and the Trade Practices Commission. Not discussed in the article is the question of excuses which can be made to avoid complying with a valid request once made, a subject which deserves its own treatment separately.
