I think a lot of the problem can be understood by clearing out the arbitrarion ruling.
The CIC is not an unreliable organization with random rulings. It's an UN sponsored arbitration panel (just to make things clear).
In Mexico arbitrarion rulings are not the same as in so many countries in which they are final. All contracts may claim that they are final in Mexico, but the reality is that still have to go thru a ratification by a judge for the ruling to be enforced.
Infored main argument is that GRC violated a provision in its contract that specified that GRC could not develop and air other news programs. The 690 station (when it was not part of GRC but an independent entity) had a news program hosted by Nino Can�n and Jacobo Zabludovsky (the current host of Monitor in GRC). So the suit by Red claims that after 690 radio station was incorporated into GRC, that became a violation of the contract they had with GRC.
It's fair from being a clear case, and that's why the ruling was not unanimous (2 x 1). The ruling was absurd, the company lost the $15 million it has paid for the contract, plus another $21 million in damage, plus the loss of a 'non-compete' by which Infored could not air 'Monitor' in other stations.
Infored will not be able to compete with GRC as their stations are not in FM. So basically it's all about the legal issues.
