I would suggest that it's the same criteria that you are deemed to have met that you will be obliged to rebut, depending on the circumstances. The assessment will indicate the nature of the factors that make you considered to be dangerous. It may not be a pattern of behaviour. It may be one of the other criteria that are set out in paragraph (a) or (b). It's not both that need to be proven. Whichever you are deemed to have met will be what you are required to rebut if, on the basis of the evidence, you can rebut that.
