Subject to subsection (2) of this section, an assay office may at their discretion cancel, or obliterate any mark of the character of a hallmark (whether appearing to be an approved hallmark or to be a mark which in the opinion of the assay office is likely to be confused with such a hallmark) which an article coming into their custody or possession bears and which the assay office are satisfied—
a
has not been struck thereon by an assay office according to law; or
b
is not a true description because the article appears to have been the subject of an improper alteration.
