Because there is no way Voldemort would be able to cast the true patronus. The nessesary mindset is much to altrusitic. Hmm. Since Hermonie could likely also master the true patronus, wrecking the animal form of the spell for everyone probably shields her from excessive punishment in general as well, at least until such time as a significant number of people other than her and Harry master it. The optimal version of this play is to have Hermonie destroy the dementor present´, but that requires enough time to prep H. Timeturner?
We think it’s likely that Voldemort can’t cast it, but Lucius and the Wizengamot do not, and the only information they have regarding it being a sign of altruism is Harry’s word on the subject.
It’s even more of a stretch to say that Lucius would be convinced that Harry is not Voldemort, because the Patronus alone isn’t enough evidence.
Point. Correction: It would eventually convince Lucius that Harry isnt pottermort once the implications have been worked out and someone else indepenantly verifies what the nessesary mindset is—likely by legimens on Hermonie. It still makes Harry and Herm indespensible right away.
I’m not even completely sure that’s true. Maybe Voldemort could cast it with a sufficiently strong-willed rejection of death for himself (and for his allies), and out of hatred of dementors=death, if he knew how.
Why would Lucius be convinced by that?
… True Patronus? Voldemort?
He already interrogated Draco under Veritaserum, so he knows that Draco saw his patronus light. That seems not to have swayed him.
Also, if there were going to be a wizard to discover a charm that does something completely impossible, my bet would be on Dumbledore and Voldemort.
