1A defendant opposing summary judgment on the ground of economic duress must condescend to particulars demonstrating illegitimate pressure applied by the plaintiff that was a reason for entering the contract; bare assertions of commercial or financial distress, without evidence linking that pressure to the plaintiff's conduct, are insufficient.
2A proposed counterclaim for unliquidated damages does not constitute an arguable defence to a liquidated claim unless the defendant establishes an equitable right of set-off that impeaches the plaintiff's claim; countervailing claims arising from the same transaction are not enough.
3On the facts, the only pressure on the defendants arose from their own third-party financing arrangements and business deadlines, with no evidence that the plaintiffs applied illegitimate pressure or had knowledge of the defendants' financial position or business opportunity.
