Legal Group Says Bush Undermines Law by Ignoring Select Parts of Bills

In a comprehensive report, a bipartisan 11-member panel of the bar association said Mr. Bush had used such “signing statements” far more than his predecessors, raising constitutional objections to more than 800 provisions in more than 100 laws on the ground that they infringed on his prerogatives.

These broad assertions of presidential power amount to a “line-item veto” and improperly deprive Congress of the opportunity to override the veto, the panel said.

In signing a statutory ban on torture and other national security laws, Mr. Bush reserved the right to disregard them.

The bar association panel said the use of signing statements in this way was “contrary to the rule of law and our constitutional system of separation of powers.” From the dawn of the Republic, it said, presidents have generally understood that, in the words of George Washington, a president “must approve all the parts of a bill, or reject it in toto.”

If the president deems a bill unconstitutional, he can veto it, the panel said, but “signing statements should not be a substitute for a presidential veto.”

The panel’s report adds momentum to a campaign by scholars and members of Congress who want to curtail the use of signing statements as a device to augment presidential power.

At a recent hearing of the Senate Judiciary Committee, the chairman, Arlen Specter, Republican of Pennsylvania, said Mr. Bush seemed to think he could “cherry-pick the provisions he likes and exclude the ones he doesn’t like.” Senator Patrick J. Leahy of Vermont, the senior Democrat on the committee, said the signing statements were “a diabolical device” to rewrite laws enacted by Congress.

Justice Department officials dismiss such criticism as unjustified. “President Bush’s signing statements are indistinguishable from those issued by past presidents,” said Michelle E. Boardman, a deputy assistant attorney general. “He is exercising a legitimate power in a legitimate way.”

Michael S. Greco, the president of the bar association, who created the study panel, said its report highlighted a “threat to the Constitution and to the rule of law.”

At its annual meeting next month, in Hawaii, the association will consider several policy recommendations, including a proposal for judicial review of signing statements.

The panel said, “Our recommendations are not intended to be, and should not be viewed as, an attack on President Bush.” The panel said it was equally concerned about the precedents being set for future chief executives.

The panel acknowledged that earlier presidents, including Andrew Jackson, Ulysses S. Grant, Theodore Roosevelt and Franklin D. Roosevelt, had occasionally asserted the right to disregard provisions of a law to which they objected. Under Bill Clinton, the Justice Department told the White House that the president could “decline to execute unconstitutional statutes.”

But the panel said that Mr. Bush had expressed his objections more forcefully, more often and more systematically, “as a strategic weapon” to influence federal agencies and judges.

In his first term, the panel said, Mr. Bush raised 505 constitutional objections to new laws. On 82 occasions, he asserted that he alone could supervise, direct and control the operations of the executive branch, under a doctrine known as the “unitary executive.”

Whenever Congress directs the president to furnish information, Mr. Bush reserves the right to withhold it. When Congress imposes mandates and requirements on the executive branch, the president often says he will read them as advisory or “precatory.”

When Congress tries to define foreign policy — for example, on Russia, Syria, North Korea or Sudan — Mr. Bush objects. Even if he agrees with the policy, he asserts that the Congressional directives “impermissibly interfere with the president’s constitutional authority” to conduct foreign affairs.

Whenever Congress prescribes qualifications for presidential appointees, Mr. Bush complains that this is an intrusion on his power, even if Congress merely requires that the appointee know about the field for which he will be responsible.

When Congress requires outreach or affirmative action for women or members of certain racial or ethnic groups, the president demurs, saying such provisions must be carried out “in a manner consistent with the requirements of equal protection under the Due Process Clause of the Fifth Amendment to the Constitution.”

The panel said Mr. Bush’s signing statements often used the same formulaic language, with “no citation of authority or detailed explanation.” It urged Congress to pass a law requiring the president to “set forth in full the reasons and legal basis” for any signing statement in which he says he can disregard or decline to enforce a statute.

In another recommendation, the panel suggested legislation to provide for judicial review of signing statements. It acknowledged that the Supreme Court had been reluctant to hear cases filed by members of Congress because lawmakers generally did not suffer the type of concrete personal injury needed to create a “case or controversy.” But the panel said that “Congress as an institution or its agents” should have standing to sue when the president announces he will not enforce parts of a law.

The issue has deep historical roots, the panel said, noting that Parliament had condemned King James II for nonenforcement of certain laws in the 17th century. The panel quoted the English Bill of Rights: “The pretended power of suspending of laws, or the execution of laws, by regal authority, without consent of Parliament, is illegal.”

The panel was headed by Neal R. Sonnett, a criminal defense lawyer in Miami. Members include former Representative Mickey Edwards, Republican of Oklahoma; Bruce E. Fein, a Justice Department official in the Reagan administration; Harold Hongju Koh, the dean of Yale Law School; William S. Sessions, a former director of the Federal Bureau of Investigation; Kathleen M. Sullivan, a former dean of Stanford Law School; and Patricia M. Wald, former chief judge of a federal appeals court.
