Unfortunately in the US if your law isn't that specific - and almost any law about "impact, fairness, and accountability" is going to be much harder to tighten up, interpretation-wise, than one about "don't fucking do these things" - then it's a big target for judges who don't like your definition of impact/fairness/accountability, or the definition of the agency you create to oversee it. That's why the Republican party has been gunning so hard in the past couple decades for the Chevron deference precedent: they want it harder to have legally-enforceable regulations that don't require lawmakers to get into the weeds (and risk being narrow and outdated soon).
