Mercedes warned in 2012 there was no scope for F1 in-season testing
"Pirelli is entitled under the terms of their agreement with the FIA to offer teams 1000km of tyre testing, subject to each team being treated equally," said the email.
"However there are no provisions within the Sporting Regulations for such testing to take place in-season.
"[FOTA has] spoken with Charlie [Whiting] to confirm the process going forward, and there are two options: 1. ALL teams want to take up Pirelli's offer and this is communicated to the FIA who will amend the Sporting Regulations; or 2. The test takes place out of season (and then the testing agreement comes into play)."
