Excerpt

At issue in this appeal is the breadth of federal preemption under Title II of the federal Clean Air Act, 42 U.S.C. §§ 7521 to 7590, for claims that pertain to: (1) the initial manufacture and installation of "defeat device" software in emissions control systems in automobiles, and (2) post-sale software updates of emissions control systems during manufacturer recalls. The State of Tennessee brought this action against several automobile manufacturers for violating state anti-tampering laws by tampering with the emissions control systems in more than 8,000 of their "clean diesel" vehicles that were registered and operated in Tennessee from 2008 to 2015. The manufacturers responded by filing Tenn. R. Civ. P. 12.02(6) motions to dismiss arguing that all of the claims were preempted by the federal Clean Air Act. The trial court dismissed the claims that pertained to the initial manufacture and installation of emissions control systems for automobiles as expressly preempted by Section 209(a) of the act however, the court denied the manufacturers' motions to dismiss the claims that pertained to the post-sale software updates of emissions control systems during manufacturer recalls. We have determined that all of the State's claims are preempted by the federal Clean Air Act. Therefore, we affirm the dismissal of the claims related to the initial manufacture and installation of emissions control systems, reverse the decision to deny the Rule 12 motions to dismiss the post-sale software updates and installations, and remand with instructions to dismiss all claims.

What This Ruling Means

**What happened:** The State of Tennessee sued Volkswagen and other car manufacturers for allegedly breaking state laws by tampering with vehicle emissions systems. The case involved "defeat device" software that was built into cars during manufacturing and software updates made later during recalls. Tennessee claimed these actions violated state anti-tampering laws that protect the environment and consumers. **What the court decided:** The court issued a mixed ruling on whether federal law should take priority over Tennessee's state laws in this case. The court had to determine how broadly federal Clean Air Act regulations should override state anti-tampering laws - both for the original software installed in new cars and for software updates made during manufacturer recalls. **Why this matters for workers:** While this case primarily dealt with environmental and consumer protection laws rather than traditional employment issues, it shows how complex legal disputes between states and large corporations can affect the automotive industry. Workers in car manufacturing, emissions testing, and related fields should understand that both federal and state regulations govern their industry. When legal uncertainties arise about which laws apply, it can impact job security and workplace standards in the automotive sector.
