No, he pulled a convention that has been used between 1604 and 1920 but hasn't been needed since cos no-one tried it on.
However, the Tories can just follow the convention Atlee used in 1948 to replace the 1911 Parl Act (and thus reduce the Lords delay from 2 yrs to 1) by proroguing Parl, and starting a new session the next day with a fresh Queen's Speech.
Bet Brenda will love that.
