In English Law, it's important to distinguish between what's a civil matter and what's a criminal matter. Princess have changed the terms of the contract with a large number of their customers without consultation or offer of compensation. Now, let's suppose I choose to eat in Alfredo's every day - as was included in the fare I paid. I could go to my credit card company and ask for a refund of the charge. If they refused, I could claim it back through the County Court. In their defence, Princess could claim that the original contract allowed them to change it unilaterally but that defence would be rejected under the "Unfair Contract Terms" legislation. That is civil law - and what's confusing our contract attorney. Now, the regulator CLIA UK, will need to look into the fact that thousands of people have had their contracts altered unilaterally with Princess gaining and the customers losing. This is a scam and a criminal offence. Either CLIA UK or the Crown Prosecution Service could start criminal proceedings against Princess and if they are found guilty, the fine could be many millions of pounds and possibly they would be banned from offering cruises starting from, or calling in, the UK.
