Very quickly, just got in front of the computer again.
Cac, you say mTLD have two contracts, then in this instance the law is very clear,
it is the 'original' (first) contract that must be satisfied.
To try and bring an easy understanding of why this should and indeed has to be let us look at a man or woman who has committed bigamy (well it will lighten up the debate a little for people). When the man or woman marries their first spouse no law at all has been broken, it is only the second, third, fourth, etc. marriages when bigamy has and is being committed if they are still married to a previous spouse. (Think of all those mother-in-laws!

) In law the original contract of marriage still stands and is considered whole, the first spouse is entitled to all benefits and claims due to a legal spouse. Unfortunately all the subsequent spouces, no matter how innocent and duly deserving have no legitimate claim as a spouse because their marriage contract is nullified by the bigamists first and lawful contract of marriage.
If this were not a case of where prime contract is the lawful contract and takes presidence over all subsequent contracts can you imagine the situation, a person or company could repeatedly sell their goods until they got the price they wanted no matter how many contracts they have entered into previously. This situation would be totally absurd in the extreme.
It makes no difference in international law that the two companies are European (Irish and German). The plaintiff can start proceedings in his/her ccountry of residence or business, can start proceedings in any country where the defendants have a presence (office, etc.), or in any country where the sale occured or transmitted through (for the US see the 'Wire Act' or something similar, the one used to stop gambling by the US government). Now as we all know that Sedo has offices in the US and indeed the US office was instrumental in this fiasco, then obviously
the plaintiffs can choose to sue in the US. (I think though much effort may be expended by both Sedo and mTLD to try and discourage the plaintiffs from doing this and then in the US courts to try unsuccessfully and get it ruled as not in their jurisdiction.)
This will be a long and cumbersome affair as both Sedo and mTLD fight like cornered cats in an effort to not hand over crucial evidence of their businesses to the defendents (another major reason why it should be heard in the US courts).
As for bidders who won the first auction and then continued to bid on the second auction. I pointed out this could easily be argued as 'under duress'. Cac, you reply that 'no because they did not win the first auction'. Well they did win the first auction because it had completed. They then went on to bid again in the second auction because they 'feared' they would lose their domain names which they had entered into a contract to buy previously in the previous auction! It is timing that is important,
the first auction ended,
the second auction then begun. (On this point it should also be pointed out, as I am sure it will be to the court, the second auction did not just run the time that was supposedly lost in the first auction but for some multiple time of that claimed as lost. Further more the original winners were not directly contacted but instead Sedo invited other new bidders to join.)
Everything is to do with timing.
Now the question arises should the winners of the second auction pay for the domains. As I have said in previous posts I would urge the winners of the second auction to immediately seek their own legal advice on this matter, that would be the prudent thing to do in my opinion.
N.B. Just re-read your post Cac and I have to disagree about the level of damages. Damages could also include loss of profit, all expences involved in the lawsuit, duress to the plaintiffs and also of course punitive damages. This will end up in the millions if not tens of millions of dollars if it goes the whole hog. In the end whether it is mTLD who initially pay the claimants should they win or Sedo or some split between the two in the end it will be Sedo who pays because they appear to have acted incompetantly and negligently therefore mTLD could claim against Sedo. (Caveat: If mTLD were involved in the decision to run the second auction then their claim against Sedo could be seriously affested unless they did so at Sedo's bequest. But we do not know the situation here as neither of these parties is saying a word as they batten down the hatches against the brewing storm and tidal wave that looks like engulfing them.)
