The changes to clause 146 are consequential to having voted down clause 29. In the bill, currently subclauses 146(1) and 146(6) make a reference to proposed section 29. Now that proposed section 29 is gone, we have to get rid of subclauses 146(1) and 146(6). All this amendment does is get rid of them.
