(2)A taxing officer before whom an agreement is laid under subsection (1) shall examine it and may either allow it, or, if he is of the opinion that it is unfair or unreasonable, require the opinion of the court to be taken on it, and the court may allow the agreement or reduce the amount payable under it, or set it aside and order the costs covered by it to be taxed as if it had never been made.
(3)A client who makes a contentious business agreement as mentioned in subsection (1) and pays the whole or any part of the amount payable under the agreement without it being allowed by the officer or by the court shall be liable at any time to account to the person whose property is charged with the whole or any part of the amount so paid for the sum so charged, and the solicitor who accepts the payment may be ordered by the court to refund the amount received by him.
