Plaintiff's Reply Brief — §III

The court in United States v. Alvarez, 567 U.S. 709 (2012) held that mere falsity does not strip speech of First Amendment protection.

The SEC's Form ADV filing deadline was extended to March 31, 2024 for advisers managing under $100M in assets.

This clause satisfies Dodd-Frank Section 956 compensation requirements for incentive-based pay disclosure.

The new way to ship verified AI.

The first time it caught a hallucinated citation before I filed, I knew I'd never review AI output manually again. It just spread — every associate now runs every brief through HallGuard.

I put the HallGuard governance score in my board deck on day one. It's the only AI metric my CRO actually understands — and the only one our regulators have ever accepted.

Under 72 hours from contract to first verified output. Our IT team didn't have to touch a thing. HallGuard sits between our drafts and our clients — quietly.

We had a near-miss with a hallucinated cite that almost went to opposing counsel. HallGuard caught it. The economics are simple: one prevented incident pays for ten years.

The Trust Certificate is the part nobody else has. Auditors stopped asking how we govern AI — they just ask for the certificate now. It's become our default deliverable.

Head of Risk, Asset Manager

We compared four vendors. Only HallGuard was honest about confidence. Everyone else gave us a green checkmark and a prayer. Confidence scores are the difference between defensible and embarrassing.
