The July 19 press release does clarify the government's view, certainly, as consistent with the fact that the bill is in force. We see this recognition: The bill is in force as of royal assent in this case. There was nothing unusual with there not being a specified coming-into-force date in the bill. That's now been clarified—that the law applies—and the government is indicating its intention to introduce future legislation to address certain matters. That is something we've see before in past practices, namely, the announcement of future measures and confirmation that they're conditional on parliamentary approval.
