Paragraph 4

after paragraph 3(2) has become applicable in relation to any person a superannuation allowance under the Teachers' regulations is granted to him, and

the aggregate amount of the deductions made from his retirement pension by reason of the previous operation of that paragraph is less than the amount granted to him by way of lump sum under the Teachers' Acts or the Teachers' regulations,

for the purpose of the application of paragraph 3(1), the amount so granted shall be deemed to be the difference between that amount and the aggregate amount mentioned in paragraph (b), and

paragraph 3(2) shall cease to have any further effect in relation to him.
