There should have been gasps of relief in boardrooms across the country last Friday. Was it confidence, insouciance or ignorance that led to the deafening silence?

Last year the High Court decided that the price of data concerning horse races could only be set at cost of production plus a reasonable margin. Perhaps people read that judgment as limited to the particular facts. But it is not clear why. Had last Friday’s judgment of the Court of Appeal upheld that view, the repercussions could have been substantial.
