When lawyer Gary Friedman shared confidential documents about his biggest case with a rival attorney, he instructed her in an email to "burn after reading."

But the correspondence survived, leading a federal judge on Tuesday to reject a proposed $79 million class-action settlement between American Express Co. and millions of merchants. Another much larger settlement could be in jeopardy as well.

In a 44-page decision, U.S. District Judge Nicholas Garaufis blocked the AmEx settlement and removed Mr. Friedman from the case, citing his "improper and disappointing conduct" that "fatally tainted the settlement process."

The judge's ruling was the latest twist in two long-running lawsuits that have been rocked by the discovery that Mr. Friedman shared thousands of pages of documents and strategy with Keila Ravelo, a lawyer who worked at Willkie Farr & Gallagher LLP and represented MasterCard Inc.

Mr. Friedman represented merchants in the AmEx case and a similar but separate lawsuit that pits many of the same retailers against MasterCard and Visa Inc. Ms. Ravelo wasn't part of the AmEx case but sat across the table from Mr. Friedman in the Visa-MasterCard suit, which is in the same court but in front of a different judge.

Ms. Ravelo and Mr. Friedman were close friends who had previously worked together, according to court documents.

The Visa-MasterCard case resulted in a $6 billion settlement that already has received final approval, though lawyers representing some of the merchants are trying to unravel that pact based on the discovery of the emails between Mr. Friedman and Ms. Ravelo.

Tuesday's move by Judge Garaufis, who sits in the federal court's Eastern District of New York in Brooklyn, was particularly significant because he had granted preliminary approval to the AmEx settlement last year.

In a statement, AmEx said it was disappointed by the rejection and "we continue to believe the agreement was fair to merchants and would provide them with additional flexibility while ensuring our card members are treated fairly at the point of sale." The company also said it would continue to fight the case in court.

AmEx signed the $79 million settlement with the merchants in 2013. In addition to the payout, the pact would give merchants the right to surcharge customers who use an AmEx credit or charge card.

Mr. Friedman, who runs a firm called Friedman Law Group LLP, couldn't be reached for comment.

Ms. Ravelo, who no longer works at Willkie Farr, separately has been charged by the U.S. attorney's office in New Jersey with conspiracy to commit wire fraud to fraudulently obtain more than $5 million from Willkie Farr, another law firm and MasterCard, according to authorities and court records.

Her lawyer, Steve Sadow, said in a statement Tuesday that "we will not be in a position to comment publicly until there is a ruling on the Visa/MasterCard settlement."

It isn't clear if Judge Garaufis' decision in the AmEx case will have any implications for the Visa and MasterCard settlement. The merchants officially notified the card networks last week of their plans to challenge the settlement. The papers should be filed in the court next month.

MasterCard said the judge's ruling shouldn't affect its settlement, which is "the result of an extensive negotiation among many lawyers on both sides, with the close involvement of the court."

K. Craig Wildfang, a lawyer at Robins Kaplan LLP in Minneapolis, who played a key role in representing merchants in the Visa and MasterCard case, also said that he believes the $6 billion settlement will stay in place.

Mr. Friedman, who led a group of plaintiff lawyers in the AmEx case, held a lesser role in the case involving Visa and MasterCard. Some of his clients in the Visa and MasterCard case have filed a motion to vacate any fees he might earn in that matter, an amount they estimate at $32 million.

In his rejection of the AmEx settlement on Tuesday, Judge Garaufis disclosed details about the correspondence that previously hadn't been revealed publicly. Among them, Mr. Friedman sent many of the communications to Ms. Ravelo's personal email address, "suggesting an intention to keep the communications from being discovered," the judge wrote.

Mr. Friedman wrote "burn after reading" in at least two of the messages, according to the judge.

Judge Garaufis described Mr. Friedman's conduct as "egregious."

In his decision, Judge Garaufis said that he didn't need to consider other objections to the proposed settlement that were raised by some merchants because "the procedural unfairness and failure of adequate representation revealed by the Friedman/Ravelo communications requires disapproval of the settlement."

Jeffrey Shinder, a lawyer at Constantine Cannon LLP who represents merchants opposing the Visa-MasterCard settlement, said the details in the judge's order show why that one should be tossed as well.

"This lawyer was conflicted and he acted on those conflicts in ways that were clearly antithetical to the interests of merchants and competition overall," he said.

The rejection of the settlement represents Judge Garaufis's second recent blow against AmEx. Earlier this year, he ruled that AmEx's rules that prevented merchants from steering customers to cheaper cards were anticompetitive. AmEx is appealing that decision, but merchants are now permitted to encourage customers to use other cards from Visa and MasterCard.
