This depends on exactly where and how this fare was shown.
If, on going to their web site, you found a list of destinations and fares but subsequently discovered that no flights were available at those fares then they can get away with it claiming that the fare has sold out. All they have to do is prove that they sold at least one ticket at that fare.
If, on the other hand, you select a destination and a date, and the system gives you a fare quote for that destination and date, then the fare they quote must be the final fare inclusive of all taxes and charges. The only thing they are allowed to add are credit/debit card fees, as long as there is a free alternative to paying by credit/debit card.
So - if those figures came up as part of a fare quote for a specific flight then I believe they were breaking the law.
Transparency of air fares? It's next to impossible to compare Ryanair fares with other airlines since there are so many fees on top of the actual fare. I've never seen a website comparing fares with Ryanair - have anyone else?

I was just looking at Ryan Air and thinking about giving it a go, but then I had a question: Let's say the fare is 20GBP, which then they throw on their 10GBP for the credit card (I have a visa electron, but that's a dead deal now).
When I go to check in for the flight, can they say "Whoops! That'll be 6GBP sucka!" or is that final 50GBP from above the final price (presuming that my baggage is ok).
EDIT: Oohhh, I see what they did there. They just pepper in the online checking fee willy-nilly. That's really cheesy.
