Regulatory Enforcement and Sanctions Bill [HL]

As a complete stranger to these matters, I would have thought that any one of those three words would do because they imply the best way of doing something. If you do something effectively, you cannot have done it inefficiently or uneconomically. It makes no sense. I may be completely wrong; it may be necessary to have three words where one would do. I would have thought, however, that if you say that something should be done effectively, that should be the end of the matter.
