Mr. Cathal Guiomard:

Currently, the lion's share of consultancy costs are legal fees. We have had eight judicial reviews of decisions of the office in the past ten years. We have defended the office's decisions successfully in seven of those eight cases. Substantial legal costs arose from that, most to the greatest extent in the early years of the office, as would have been seen on the chart distinguishing core and non-core costs. There are fewer legal actions now with less in costs arising as a result. That accounts for the bulk of the money. There were some economic consultancy costs in years where we were carrying out price reviews and we needed engineering advice that was not available to us within the office. The classification also includes slot scheduling. We pay a professional services firm to do the slot scheduling role at Dublin Airport.
