There's good news for Dublin motorists this morning (finally, we hear you scream!).

The Revenue Commissioners has lost a long-running case it took to the European Court of Justice over taxing the M50 and Port Tunnel.

The Tax Man believed VAT should be applied to the cost of the tolls on both routes.

However the Department of Justice and Transport Infrastructure Ireland disputed this, arguing the state body can't tax state-owned roads.

Initially it looked like Revenue was going to win its case which would have meant price hikes of 60% for ordinary motorists.

But yesterday the ECJ ruled that because the M50 and Port Tunnel aren't in competition with privately-run roads, VAT need not apply.

Had it gone the other way drivers with tags would have seen the M50 fare rise from €2.10 to €2.50, with non-tag users facing a €3.80 toll per journey.
