I think what you said is completely accurate.
When we're considering cases and they're referred to the IRB, there are a number of reasons we might want to intervene. Misrepresentation might be one of them and likewise criminality, but officers have that discretion. In the case of somebody who overstayed a visa one time, it's hard to say if that officer would decide, on the scale or balance of probabilities, that it might be worth an intervention to the IRB to interfere in an asylum claim.
