The general approach to rule-breaking in a lot of areas is tolerance if it does not matter, but if you break the rules, and it matters, it is your fault.
If you drive in England with a light missing because the bulb has failed, a policeman might stop you, but if he does he will merely mention you should get it fixed. On the other hand if there is an accident, then the fact your lights were not working properly will be taken into consideration when fault is determined.
Similarly we know well that spoken answers to questions are common behind screens, and are generally tolerated. But when there is a dispute, tolerance is no longer acceptable. East claimed a response that made him let through the contract: he should have made sure he got responses in writing: he did not: he has no legal claim.
In the case of the car it is my responsibility to fix the light. In the bridge case it is Explainer's responsibility to write the answer. Surely the lack of written explanation should count against North at least as much as against East.
