Section 143

In any legal proceedings in which the validity of a registered trademark comes into question and is decided in favour of the registered proprietor, the Court may certify to that effect, and if it so certifies then in any subsequent legal proceedings in which the validity of the registration comes into question the registered proprietor on obtaining a final order or judgment in his favour shall have his full costs, charges and expenses as between solicitor and client, unless in the subsequent proceedings the Court certifies that he ought not to have them.
