Illustrative example
Leaseholders succeed at the tribunal on a major works challenge. Months later the freeholder's solicitors' fees for defending it appear as a line in next year's service charge, so the leaseholders would end up paying for both sides.
Section 20C lets a tenant apply for an order that the landlord's costs of the proceedings are not to be regarded as relevant costs in determining the service charge payable. The test in subsection (3) is simply what is just and equitable in the circumstances - there is no presumption either way, and winning does not make the order automatic. The fact of timing matters: subsection (2) points the application at the body hearing the case, so it is normally made at the end of the substantive hearing rather than later.
The freeholder agrees to remove the legal costs line from the service charge account in full, and the leaseholders agree to make no application for their own costs.
