You can see why Leonard Nelson was so perturbed by Einstein's Theory of Relativity. It goes against the major argument of the Critique of Pure Reason.[The Transcendental Analytic] Kant proves there is an objective order of events. (Plus causality. That is not against Relativity but it seems to be somewhat of a problem in Quantum Mechanics). He takes nine closed argued steps to prove this. [And to me it seems not clear if Friesian concepts can help Kant. 

[As for the first point, in some way Kant was right because events [for one observer] to be taken in reverse order [by another observer] would be out of one of the light cone of one of those observers. Kant wants events in the mind to have an objective order in time. And that is true. But then to apply that to the world outside one's mind is what he is trying to prove --in order to disprove sceptic claims about reality. But there is where the proof seems to fail. I mean to say Kant wants to prove that we have a priori knowledge of the phenomenal world--for example we know causality.(He goes with Newton as opposed to Leibniz.)  [Clearly Kelley Ross would have an answer for this that is. After all Gretta Herman found the reconciliation between Relativity and the Friesian School. Still, it seems that this is some area that shows a problem.] 

[One thing I might mention. Kant was trying to refute Berkley. {It is all in the mind} He wanted to prove causality and simply existence of the objective world. But the way he must causality is events which happen according to a rule." Well That is certainly true. when the particles coming out in EPR [Einstein Podolsky Rosen] decide to refrain from being upor down spins until they interact, they are doing so according to a rule.
