I agree Pete that there is a sensible answer to this in the future but let's be honest, sensible answers and the FAI/League don't generally go hand in hand.
If Derrry do go to court to challenge a decision it would not be sufficient for the FAI to show through their mail server that the e-mail was sent, they would have to show that the e-mail was received.
Most fax machines print out a sheet after a fax is sent which indicates with an 'ok' or a 'failed' whether the communication was successful. If the FAI/League have this I think it would be accepted that the fax was sent and received.
Anybody know if the rule book specifies by what method notice of a suspension can be communicated?
