From the court’s decision:

<<But this new law generated several years of international-trade issues with Canada and Mexico, including two disputes before the World Trade Organization and more than $1 billion in retaliatory tariffs imposed against the United States. … … As a result, in 2015, Congress repealed the new country-of-origin requirements for beef products, essentially reinstating the pre-2008 status quo.>>

The court just used this “status quo” law formulas. But it’s not the result of just lobbying, right. It’s the result of a trade war.
