Long before she was a Justice, Ruth Bader Ginsburg was a litigator, and as a litigator she did something only the greatest advocates ever manage. She changed what the Constitution was understood to mean, not with one dramatic case, but with a patient campaign of small, winnable steps, argued so carefully that the Court moved without quite realizing how far it had gone.

She came up at a time when the law barely saw the problem she set out to solve. She had graduated at the top of her class at Columbia and still struggled to be hired, because she was a woman. In 1972 she co-founded the Women’s Rights Project at the ACLU, and from that perch she began to argue, before an all-male Supreme Court, that treating men and women differently under the law was a constitutional problem. She argued six of those cases and won five.

Her genius was strategic. She understood that nine male justices might not feel the sting of a law that held women back, so again and again she brought them the mirror image. She represented men. A widower denied the survivor benefits a widow would have received. A man denied a benefit because the law assumed only women did the caregiving. By showing that laws built on assumptions about the sexes hurt everyone who did not fit the mold, she let the Court strike down sex discrimination without asking it to take anyone’s side in a culture war. She made equality look like common sense, because she framed it that way.

And she was patient in a way that ambitious lawyers usually are not. She did not ask the Court for everything at once. She asked for one clear step, won it, and then used that win as the ground for the next case. Reed, then Frontiero, then Wiesenfeld, then Duren, each one a little further than the last. She was building a staircase, and she refused to skip a stair, because she knew a court will climb slowly what it will not leap. It is one of the most disciplined pieces of long-term litigation strategy in American law.

For a lawyer, the lessons are concrete. Pick the case, and the client, that makes your principle impossible to resist, not the one that makes the biggest headline. Frame your ask so the decision-maker can say yes without feeling he has crossed a line. Win small before you try to win big, and build each argument on the one that came before. This is how you move a body that does not want to be moved, and it works in a courtroom, a mediation, or a negotiation just the same.

She was famously, almost punishingly, prepared, and famously calm. She did not raise her voice or trade in outrage. She let the structure of the argument do the work, one careful sentence at a time, and she trusted that a well-built case, laid out plainly, was harder to refuse than a loud one. In an era that rewards volume, that is a discipline worth studying.

She went on to the appeals court and then to the Supreme Court, and the rest of that story belongs to a different series. But the advocate is the one to learn from here. Ruth Bader Ginsburg proved that a single lawyer with a strategy and the patience to follow it can change the law of the land, not by shouting it down, but by walking the court, step by careful step, to a place it did not know it was going. That is advocacy at its highest, and it is worth every hour of study a trial lawyer can give it.

Ruth Bader Ginsburg (1933 to 2020), considered here as the litigator she was before she took the bench: co-founder of the American Civil Liberties Union Women’s Rights Project, who argued six sex-discrimination cases before the Supreme Court and won five, among them Frontiero v. Richardson, Weinberger v. Wiesenfeld, and Duren v. Missouri, and who wrote the brief in Reed v. Reed. Considered here for the craft of advocacy and litigation strategy, not for her later service and not for politics. This is general information, not legal advice.
