Premises & conclusion as we read each side

EPA Administrator · speaker A

P1. Clean Air Act §202 contains no explicit grant of climate-regulatory authority.

P2. Loper Bright Enterprises v. Raimondo (2024) ended Chevron deference; agency interpretations of ambiguous statutes no longer bind courts.

P3. West Virginia v. EPA (2022) requires clear congressional authorization for agency rules of "vast economic and political significance."

Unstated. GHG regulation under §202 qualifies as a major question; congressional silence equals withholding of authority.

C. EPA cannot regulate GHGs under §202 absent fresh congressional authorization.

Member of Congress · speaker B

P1. Climate change drives flooding, air pollution, and rising healthcare costs in constituents’ districts.

P2. EPA holds a duty under §202 to protect public health from air pollutants, and GHGs are pollutants per Mass. v. EPA.

P3. Current EPA actions favor polluting industries while invoking "growth" as cover.

Unstated. The duty to protect public health overrides interpretive concerns about agency authority.

C. EPA must continue regulating GHGs for climate.

Scores

Each side judged independently against the same rubric, blind to the other. 1–10 per criterion.

Criterion EPA Admin. Member of Cong.
1. Fidelity to statutory text 10 3
EPA reads §202 narrowly and identifies the textual silence on GHGs accurately. The Member treats §202’s public-health language as covering climate without engaging the statute’s "ambient air pollutant" framing or the listing structure.
2. Adherence to controlling SCOTUS precedent 10 2
EPA cites Loper Bright and WV v. EPA by name and applies the major-questions doctrine on point. The Member invokes Mass. v. EPA but does not address how 2022–2024 cases narrowed it; the precedent gap is dispositive.
3. Logical structure and coherence 9 6
EPA premises chain cleanly to the conclusion. The Member’s argument is internally consistent as advocacy but conflates moral duty with legal authority, weakening the inference.
4. Evidence vs. policy preference 7 3
EPA cites two named cases and a statutory section. The Member cites district-level harms (real and important) but offers them as evidence for the legal conclusion they don’t establish.
Overall (sum / 40) 36 14

Synthesis

On the rubric of statutory interpretation under current SCOTUS precedent, the EPA Administrator’s argument scores higher across all four criteria. The Member of Congress’s case is coherent as policy advocacy but does not engage the controlling cases — the gap is largest on text and precedent, where the rubric is most demanding.

A different rubric — public-health policy tradeoff, say, or democratic accountability — would likely score them differently. That’s the point of publishing the rubric. Disagree with the rubric choice?

DebateGrader scores arguments on the rubric chosen, not the truth of underlying claims. Fact-checking is out of scope. This run was scored on-demand from a tag mention.
