The score adds the points of each distinct live case: one point for taking part plus up to two for the case’s significance, rated as for the main index. Calculations use full precision, and displayed points are rounded to two decimal places. Co-counsel receive full credit. A dash in the value column means no usable dollar figure is recorded. Recorded values are approximate and are not necessarily recoveries. This ranking measures participation in major disputes, weighted by their significance, not legal ability or wins.
