In some circumstances what you're dealing with is that there's no statute of limitation on misrepresentation.
The example Mr. Fogel gave of a misrepresentation in 1954 is a very serious misrepresentation. There's no doubt that in those circumstances it may well be appropriate to go after somebody who misrepresented themselves 60 years ago. However, in other cases, if somebody.... Take the example of the engineer that I gave you earlier, if they misrepresented 60 years ago and have since become an engineer and have established themselves here, there may be factors that make taking their citizenship away unfair, even though technically they did misrepresent.
There's a big difference between the scope of the misrepresentations we're talking about and the context of somebody's status—how long they've been here and their establishment here. I would say those factors are relevant here and should be considered.
