I think there are a couple of things that must be part of fair stewarding.
1) You're punishing the incident, not what effect the incident has on the race.
2) It cannot matter who the drivers are.
I don't know how the stewarding system works now, but I imagine that the stewards know the effect on the race, and who the drivers are. I think the stewards should not be allowed to watch the race. They are in a room with no access to F1 media/data. When they are referred an incident, they only see the incident, and all details of the car and driver are whited out. All the stewards would see is the white outline of the two cars, and they would have to make their decision based upon that. The two cars could be Hamilton v. Massa, Kovalainen v. Pic, or Alonso v. Karthikeyan.
This is a quickly thrown together example of what the stewards would see.
In the above example, they would only see from just before the attempted pass of Car 2 (right) by Car 1 (left) The only thing that matters is whether Car 1 forced Car 2 off the track in violation of the regulation. Nothing else is required. They don't get to know if Car 2 passed Car 1 immediately, or soon after. They don't get to know if Car 2 crashed out as a result. They don't get to know if Car 1 retired due to an unrelated technical problem. The same with last week in Belgium. They would only get to see up until the point that Hamilton went off track. They would not get to see the resultant crash that took out other drivers.
