I've taken another glance at the
NI Act that was meant to stop Parliament from being prorogued. Here's the relevant part:
So a report is required before Parliament on or before the 4th of September, there must be a debate in Parliament within 5 days, then a further report on or before the 9th of October (and debate), then every 14 days. If Parliament is prorogued, Parliament will be required to meet for the report of debate anyway.
The 9th of October is
before the planned prorogation ends.
My reading of things is as follows: The Government could present their report next week (as required), hold the debate, and then present a second report immediately. But the language of the act appears to require further reports every 14 days after the second report, as opposed to every 14 days after the 9th. If that is the case, Parliament will have to meet and conduct business during the prorogation anyway.
