I would imagine that the whole thing would depend on the wording of the offence- if it is something along the lines of "passing the stop line whilst the light is red" then you need to establish how they define "passing".
i.e. if you had your front wheel over the line but not the rear then you might be able to suggest that you had not gone past the line.
However, if you had both wheels clearly past the line then this would not be an option.
