The plaintiffs sold a construction business to the defendants, with a portion of the purchase price secured by a vendor take back promissory note.
The defendants refused to pay the note, claiming set-offs for intercompany debt, retained bank balances, and a bookkeeping error that overstated accounts receivable.
The court held that the purchase price was fixed and not subject to adjustment for the intercompany debt, and that the bookkeeping error did not constitute a breach of warranty.
However, the court allowed a set-off for the retained bank balance, which the plaintiffs conceded should have been transferred on closing, reducing the amount owing on the promissory note.
