Keith Hackett's verdict
1) It's unconventional, but let him make the change. A substitution can be made at any time, provided the team has not used up its allocation. So allow him to make the change before the restart. Thanks to Salah Salah.
2) This happened to me in the 1981 FA Cup final: both my linesmen started to patrol the same half. Fortunately they adjusted before having to make a decision. These days it should be impossible as assistants are told to operate on the right wing, and you should check with them before blowing for kick-off. But if this scenario did take place, talk to both, ask why they think the goal should or should not stand, go with whichever option you think is correct and then restart with the assistants back in their correct positions. Ryszard Kaleta wins the shirt.
3) You've made a bad mistake here: you should not be basing any decisions on guesswork. It is too late, though, to withdraw the yellow card you've shown – if you did that, you would be effectively agreeing that there had been an act of violent conduct, which you also didn't see. So stand by the decision and then explain everything in your post-match report. You also cannot use the excuse of him removing his shirt for the second yellow – that is only an offence when celebrating a goal. Thanks to David Millward.
