The first handler of sea urchin being assessed shall deduct the assessment from amounts paid by him or her to the diver, and shall be a trustee of these assessments until they are paid to the commission at the time and in the manner prescribed by the commission. Failure to collect the assessment from any diver shall not exempt the handler from liability. In addition, failure of a handler to remit the collected diver assessments to the commission shall not relieve the diver of this obligation.
