This is old hat. Blame too much summer travel. It is worth highlighting nonetheless.
The High Court ruled in favour of a private bus company, trying to compete with Dublin Bus. The judge said the regulator was wrong to allow the subsidized, state-owned incumbent to share a route with a private operator. The judge berated the consultant to the regulator. The judge also ruled that the regulator wrongly delayed the processing of an application for a second license.
This is good news in itself, and it sets a precedent for future cases (although the legislation is about to change).
Note that the High Court implied that, for urban bus transport, competition should be for the market rather than in the market. That is right for all but the busiest routes.
