Lord Denning MR doubted the applicability of the criteria in American Cynamid to public law proceedings. It is appropriate at the interface of public law and private law for the public interest to be taken into account as one of the factors in the balance of convenience.
Browne LJ said: ‘where a defendant is a public authority performing duties to the public one must look at the balance of convenience more widely, and take into account the interests of the public in general to whom these duties are owed.

Ethicon Ltd  1 All ER 504 at 511,  AC 396 at 408.’
