Yeah, they could put forward essentially the same legislation, and if they found proper evidence that the legislation actually meets the goals it was stated to address, they easily win this case.
There's a reference in there to the "speed limiter" case. In that case, which challenged legislation that forced truckers to have their speed limited to 105 km/h, the truckers brought evidence that there were situations where that rule was detrimental to their safety because they couldn't accelerate out of a dangerous situation. But because the government had other objectives, and had evidence that the legislation accomplished those objectives, it was permitted to make that safety trade-off.
