Oakland lawyer Jon Eisenberg calls the case of Al-Haramain Islamic Foundation v. George W. Bush the strangest he has ever handled. How strange? Eisenberg was required to write one of his briefs in a windowless government office, without notes or lawbooks, under the watchful eye of two federal security guards.

When he got hungry, one of the guards brought him a banana. And when he finished, a security official shredded all his drafts — and even the banana peel, Eisenberg said.

The brief-writing session was just one facet of the extraordinary secrecy surrounding the Al-Haramain case, Eisenberg said. Al-Haramain is one of dozens of plaintiffs across the nation that have filed suit, claiming they were illegally spied on by the government as part of the war on terror.

In most of the cases, including Al-Haramain’s, the government has contended that any disclosure about the surveillance program would reveal state secrets and has refused to say whether the plaintiffs were wire-tapped. It has then moved to dismiss the complaints.

But in the Al-Haramain case, the Treasury Department inadvertently disclosed National Security Agency call logs stamped "top secret" indicating that the charity and two of its attorneys had been surveilled. Last year, U.S. District Judge Garr King ruled that the logs — referred to in the court papers as "The Document" — gave the charity standing to sue in federal court.

Today, Eisenberg and Justice Department lawyer Thomas Bondy will each have 20 minutes to argue over King’s decision before a three-judge panel of the U.S. 9th Circuit Court of Appeals. Although the argument will be conducted in public, much of the information in the case, including what was in "the Document," remains veiled in mystery.

Many of the government’s motions have been filed under seal, and those lodged publicly contain gaps; one government brief reads: "REDACTED TEXT. PUBLIC TEXT CONTINUES ON PAGE 6."

Some of Eisenberg’s briefs have been redacted as well, because they are considered too sensitive for the public to see. But although Justice Department lawyers can see Eisenberg’s redactions, he isn’t allowed to see theirs.

In the Al-Haramain case, Eisenberg has had to respond to a government filing he was not allowed to see.

Asked Monday if there was any way, under the government’s interpretation of the law, that someone could contest the surveillance program, a senior Justice Department official replied, "In the current context, no."

Georgetown University constitutional law professor David Cole, who is not involved in this case but has represented individuals in similar situations, said the Al-Haramain case presented a daunting undertaking for a lawyer — and a threat to the rule of law.
