A 1950 trust fund case still decides whether the notice of a lawsuit was good enough.

A three million dollar fund relied on small type

In January 1946, Central Hanover Bank & Trust Co. pooled 113 small trusts into a common trust fund under section 100-c of the New York Banking Law. About half had been created during life and about half under wills. The fund held nearly three million dollars in gross capital. Some beneficiaries lived outside New York.

In March 1947, the bank asked a New York court to settle its first account. The statute required notice once a week for four successive weeks in a designated newspaper.

The notice named the bank, the fund and the participating trusts. It did not name the beneficiaries. It did not give their residences. The notice was addressed generally to people with interests in the fund.

The court appointed Mullane as special guardian and attorney for people with interests in the income. James N. Vaughan represented people with interests in the principal. Mullane objected. He argued that publication alone did not satisfy due process under the Fourteenth Amendment.

New York courts overruled him. The Supreme Court reversed.

The method had to be a real attempt to reach the person

In Mullane v. Central Hanover Bank & Trust Co., 339 U.S. 306 (1950), the Court held that publication alone was enough for beneficiaries whose interests or whereabouts could not be ascertained with due diligence.

It was not enough for known people with known addresses. Those beneficiaries should receive notice “at least by ordinary mail to the record addresses.”

Justice Jackson wrote the opinion. Justice Burton dissented. Justice Douglas took no part. The decision was argued on February 8, 1950, and decided on April 24, 1950.

While checking this piece against the opinion text, the editors caught a small point. A widely used case summary calls Mullane unanimous. The opinion itself shows Burton dissenting and Douglas not participating, so the vote stated here comes from the opinion text.

The Court gave the governing rule in direct terms. Notice must be “reasonably calculated, under all the circumstances, to apprise interested parties of the pendency of the action.” The method must be one that “one desirous of actually informing the absentee might reasonably adopt.”

Publication could reach some people by chance. But “Chance alone brings to the attention of even a local resident an advertisement in small type.” That was the problem for beneficiaries whose names and addresses were known.

The point was not that newspaper notice never counted. The point was that the method had to fit what the sender knew about the person and the available ways to reach that person.

A returned letter can require another step

The Supreme Court used the same standard in Jones v. Flowers in 2006.

Arkansas mailed two certified letters about delinquent property taxes to Gary Jones’s house in Little Rock. Both came back marked “unclaimed.” The state then published a newspaper notice and sold the house to Linda Flowers for $21,042.15. The parties stipulated that the property’s fair market value was $80,000.

Chief Justice Roberts wrote for the Court. Citing Mullane, the Court held that the state had to take additional reasonable steps when mailed notice was returned unclaimed, if those steps were practicable. The Court identified examples such as sending the notice again by regular mail, posting it on the door, or addressing it to “occupant.”

The decision did not require an open-ended search for a new address. It required the state to respond to a visible failure in the first method.

That distinction matters. A method can be authorized at the start and still become inadequate when the sender learns that it did not reach the person.

The same test reaches modern service methods

Rio Properties, Inc. v. Rio International Interlink, 284 F.3d 1007 (9th Cir. 2002), applied theMullane standard to service by email.

A Las Vegas casino sued a Costa Rican online sports betting business. The business had no physical address. It used a Florida mail courier and an email address for its business. The district court allowed service by email, along with mail to the courier and the attorney. The Ninth Circuit affirmed under Federal Rule of Civil Procedure 4(f)(3).

The court said the method had to be reasonably calculated to apprise the defendant of the action and give the defendant a chance to respond. That was the same test that came from Mullane.

Courts read Rio narrowly. It does not mean email service is always sufficient. The plaintiff there had no other workable address, and the email address was one the defendant used for business.

For a law firm, the practical point is plain. A rule allowing a method is not the whole question. When a firm sends notice, attempts service or writes to a client, the method should be a real attempt to reach that person. When the firm can see that the first attempt failed, a second reasonable attempt may be needed.

Archivar is an operating system for a law firm that answers every call 24/7 in English and Spanish and runs intake. At intake, the firm learns how a person can actually be reached, and the record keeps the caller’s preferred language and contact details with the matter because Archivar remembers everything the firm does.

That makes the intake record matter later. The known address a firm relies on should be one it actually captured, not one assumed from an old form or a rule’s bare permission. When notice comes back, treat the return as new information and take the next reasonable step.

A newspaper carried the notice for four weeks.

Whether it reached a single beneficiary was the question in 1950.

It is still the first question a court asks about any notice.
