If State of California v. Orenthal James Simpson
further tarred the perpetually besieged class of Americans whose names end in Esq., the past 12 months confirm that these are the fat years of lawyer-bashing. Thanks much, Bill “That Depends How You Define ‘Is'” Clinton. Truly obliged, Ken “On All Nine of Those Occasions, the President Fondled and Kissed Her Bare Breasts” Starr. A Civil Action may break ground in lionizing ambulance chasers, but there’s nothing new in its demonization of corporate attorneys.

Maybe we love to hate them because we hate that we need them, be it to draft a will, sue our broker, or help our Ukrainian third cousin obtain that elusive work visa. In Philadelphia, we’re blessed with one of the strongest legal traditions in the country, but having 14,000 lawyers can also be a curse. How do you begin to figure out who to go to?

Well, we asked them who they’d go to.

First, we sent surveys to 4,000 Philadelphia lawyers randomly selected from the rolls of the Philadelphia Bar Association and asked which attorneys they would turn to for legal help. Next, to guard against ballot stuffing, cliquishness, parochialism and hype, we talked to more than 100 acknowledged leaders of the bar, legal head- hunters, prosecutors, clients and corporate in-house coun- sel, to make sure the survey results reflected consensus within the various practice areas. Several attorneys of great stature didn’t make the cut, because the focus here was more on day-to-day practitioners than on lawyers best known for their connections or administrative prowess.
