“Loophole” is the journal of the Commonwealth Association of Legislative Counsel.
The most recent edition of Loophole, available at Loophole - 2021-02 (2021-10-26).pdf (calc.ngo) includes an article by our own @MatthewWaddington on formal logic and its relevance as a tool for legislative drafting. It covers the basics of propositional logic, plus modal deontic concepts, specifically Hoefeldian concepts.
The paper starts at page 56 of the PDF.
