I could be wrong but I think it would be more accurate to describe it as "consults" on the regulations rather than "decides". I think that the Greek tax authority hold discussions with a group of accountants before implementing new regulations. The accountants express their opinion and point out what they think are anomalies or possible problems. The tax authority then takes account of or totally ignores the opinions. I think the latter is more common. It does mean he is well clued up, which, from his customers' point of view, is the key thing.
