By that same logic, the District Court Judge who dismissed Heller's lawsuit against the District of Columbia should have had precedence over the higher courts (first the Court of Appeals that remanded the dismissal, then the SCOTUS who affirmed Heller's lawsuit).
The question was why didn’t SCOTUS find the same obvious government coercion that a lowly District judge found?
The other dog doesn’t hunt.
The harm is obvious and was intentionally done by the government. They cannot as a matter of precedent oppress our right by proxy which is exactly what took place in this case.
