(It has been argued that the person who signed the document in fact did not have the authority to do so, but this company are having none of that)
Also , at the risk of confusing the issue, I think the registration company used a sneaky practice : the original letter suggested their business as "sporting" associated and if this was not accurate ,they were to tick the box which did accurately describe their business area. Was this a marketing ploy to encourage them to submit the document ??
