- "You filthy little beasts would never have dropped Stink pellets if you'd known I had it in my power to whip you raw, would you, now? Nobody would have thought of throwing Fanged Frisbees down the corridors if I could've strung you up by the ankles in my office, would they? But when Educational Decree Twenty-nine comes in, Potter, I'll be allowed to do them things..."
- —Argus Filch on the Decree[src]
Although never actually passed, the Educational Decree Number Twenty-Nine was going to be one of Dolores Umbridge's Educational Decrees.  When passed, this Decree would give Argus Filch the powers to physically punish the students  However, Dolores Umbridge was sacked and her Educational Decrees were abolished before she had time to do this.
Behind the scenesEdit
The non-canonical Educational Decree Number Twenty-Nine featured in the film adaptation of Harry Potter and the Order of the Phoenix gave the High Inquisitor the power to review extracurricular activities.
