A multitude of cases may be cited to show that, when used in a context such as the present, the expression "proceedings" denotes, primarily, curial proceedings though no doubt if in the instant case the debt was a secured debt, it would be wide enough to include the exercise of a right given by the security to take extracurial action for the recovery of the debt. So seizure and sale of goods or the appointing of a receiver under powers conferred upon the creditor by the security might, in such a context, be properly regarded as the taking of proceedings. But a mere written demand for payment and a threat to present a winding-up petition at some future time has none of the characteristics of curial proceedings or of the exercise of rights given to a creditor by his security. Section 222 (2) (a) does not authorize, and does not purport to authorize, a creditor to make a demand for payment upon his debtor; a creditor needs no statutory authority for this. All that s. 222 (2) (a) does is to provide a convenient method of proof, if a debtor company for three weeks after service of a demand neglects to pay the sum due or to secure or compound for it to the reasonable satisfaction of the creditor, that a company is unable to pay its debts which, by virtue of the earlier sub-section is a ground for winding up.
