It's in connection with ticket sales for the Oasis reunion concerts at Croke Park last year.
Ticketmaster has been accused of breaching consumer law in connection with ticket sales for the Oasis reunion concerts at Croke Park last year.
The case was before Dublin District Court this morning, and stems from an investigation by the CCPC.
Ticketline Unlimited Company, trading as Ticketmaster, faces two charges under the Consumer Protection Act over information provided to Oasis concertgoers who bought Platinum tickets.
The first charge alleges that the firm engaged in a misleading commercial practice by offering "Platinum" tickets in a manner likely to deceive consumers regarding the product's main characteristics and specifications.
The second alleges that Ticketmaster provided material information concerning ticket prices in a manner that was unclear, unintelligible, ambiguous, or untimely.
A representative for the company told the court he anticipated the case "will be fully contested" and advised that the defence believed it would call a dozen or so witnesses and expert evidence.
The prosecutor said he had informed the defence he would seek a four-week adjournment to deal with disclosure and evidence.
The judge adjourned the case for mention until 5 October.
