The right hon. Gentleman makes the same mistake that the SNP Front-Bench team made. Contrary to narrowing the definition, proposed new subsection (3A) in amendment 4 states:
“The cases in which a person has a reasonable excuse for the purposes of subsection (3) include (but are not limited to) those in which at the time of the person’s action or possession, the person did not know, and had no reason to believe”.
There is no finite list. The legislation is as broad as possible to include a whole range of reasonable excuses, including ones that we have not even thought about.
