The amendment I am proposing makes the measure retroactive to the date on which the budget was brought down, that is, the date on which the measure was announced. If I understood correctly, my colleague's amendment makes the measure retroactive to a time before that date.
The reason we chose the budget date as the date for this to go into effect, is to clearly mark the point at which the measure was announced, so that there could be no retroactivity before the date of the announcement. Clearly, I much prefer my motion.
