“If, without invitation from the court, the company volunteers a submission or attendance, the company will not normally be allowed any costs of that submission or attendance. The aim is that unmeritorious claims will be disposed of without the company becoming involved, in much the same way that unmeritorious appeals are resolved without the respondent to the appeal being required to participate.”
“Nevertheless, there are situations in which it would plainly be appropriate for a company to participate prior to the claimant successfully demonstrating a prima facie case, and where a company might expect to displace the usual rule precluding the recovery of its costs of doing so. If the company has a knock-out point that can be swiftly, cheaply and incontrovertibly deployed, then it is submitted that the company's participation would be appropriate.”
