The 80/20 rule — also called the Pareto Principle — comes from Italian economist Vilfredo Pareto, who noticed about a century ago that 20% of the people in Italy held 80% of the wealth. In the legal world, lawyers apply the idea two ways.
Some attorneys apply it to their practice: 20% of their cases generate 80% of their revenue, so they focus on the high-value cases where the most is at stake. More importantly for a client facing a DUI charge, the 80/20 rule also applies to case strategy. Roughly 80% of successful DUI outcomes come from 20% of the legal strategies — challenging the validity of the traffic stop, questioning breathalyzer calibration and maintenance records, scrutinizing the officer's field sobriety test administration, examining probable cause, and reviewing the chain of custody on any blood or breath evidence.
A DUI lawyer who understands the 80/20 rule focuses on the critical few elements that actually move outcomes, rather than scattering effort across every detail of the case. When you're interviewing a DUI attorney, ask what strategies they prioritize first when reviewing a case — their answer tells you whether they know which 20% to work.
