Amlord,
Actions can be considered unconstitutional. The President's actions – using signing statements in this manner – violate the Presentment Clause. The President can't sign a piece of legislation into law disapproving of certain sections (believing them to be unconstitutional) and then just say he'll ignore the unconstitutional parts of the legislation. The Constitution very clearly states that if the President does not approve of a piece of legislation he vetoes it in its entirety – to do otherwise violates the Constitution.
Bernard Nussbaum's memo explains that this is not un-Constitutional and has in fact been used by Presidents exactly in this manner dating back to at least Thomas Jefferson.
The memo explains, as I did with another basis, the historical uses of the Presidential signing statement and the "selective" enforcement of statutes.
In the case of torture (which the President has said the US will not use), there may be a conflict between the bill and Presidential powers. Bush was merely reserving the right (and informing Congress of this fact) to use the means within his power to protect US citizens from attack. This is not an indication that he approves of torture, it is simply a statement to Congress that he will not allow them to encroach upon his Constitutional duty.

Amlord dubs this an unfair question, but his reasoning misses the mark. If the signing statement has the effect of representing a line item veto (ie. I'll enforce what I want to enforce), he is violating the presentment clause by function. I'm not sure if "more unconstitutional" is really valid, but it seems to exceed the reasoning from the line-item decision because at least in that scenario Congress had an ability to challenge the line item decision. In the current context, Congress has no clear recourse when a signing statement effectively guts the intent of the law. If they simply pass another law, the President can simply append another statement. That is an unchecked power by the executive branch.
Your analysis is different from the Clinton Department of Justice and the Bush Department of Justice. I have cited court cases where state officials can be held personally liable for enforcing laws which are un-Constitutional.
If a bill is dubious and could be viewed as unConstitutional, the President can elect to choose an enforcement interpretation that will allow the bill to withstand Constitutional review. The Supreme Court has used this approach (as reference in Nussbaum's memo):
QUOTE
Thus, the President may use a signing statement to announce that, although the legislation is constitutional on its face, it would be unconstitutional in various applications, and that in such applications he will refuse to execute it. Such a Presidential statement could be analogized to a Supreme Court opinion that upheld legislation against a facial constitutional challenge, but warned at the same time that certain applications of the act would be unconstitutional. Cf. Bowen v. Kendrick, 487 U.S. 589, 622-24 (1987) (O'Connor, J., concurring). Relatedly, a signing statement may put forward a "saving" construction of the bill, explaining that the President will construe it in a certain manner in order to avoid constitutional difficulties. See Federal Election Comm'n v. NRA Political Victory Fund, 1993 U.S. App. LEXIS 27298 (D.C. Cir. 1993), at *11-*12 (Silberman, J., joined by Wald, J.) (citing two Presidential signing statements adopting "saving" construction of legislation limiting appointment power). This, too, is analogous to the Supreme Court's practice of construing statutes, if possible, to avoid holding them unconstitutional, or even to avoid deciding difficult constitutional questions.
Let's look at the examples given in the Boston Globe:
QUOTE
March 9: Justice Department officials must give reports to Congress by certain dates on how the FBI is using the USA Patriot Act to search homes and secretly seize papers.
Bush's signing statement: The president can order Justice Department officials to withhold any information from Congress if he decides it could impair national security or executive branch operations.
National security is in the hands of the executive. While this may seem controversial, it shouldn't be. Given the history of leaks coming out of Congress, some caution is advised.
QUOTE
Dec. 30, 2005: US interrogators cannot torture prisoners or otherwise subject them to cruel, inhuman, and degrading treatment.
Bush's signing statement: The president, as commander in chief, can waive the torture ban if he decides that harsh interrogation techniques will assist in preventing terrorist attacks.
Again, national security. The President has said that we will not use torture, but to allow Congress to say that is a breach of the Separation of Powers (at least in the mind of the President).
QUOTE
Dec. 30: When requested, scientific information ''prepared by government researchers and scientists shall be transmitted [to Congress] uncensored and without delay."
Bush's signing statement: The president can tell researchers to withhold any information from Congress if he decides its disclosure could impair foreign relations, national security, or the workings of the executive branch.
Again, national security. Members of Congress are not privy to all of the nuclear secrets of this country (although select committees are). The broad nature of the law would allow any Congressman to ask for highly sensitive documents.
QUOTE
Aug. 8: The Department of Energy, the Nuclear Regulatory Commission and its contractors may not fire or otherwise punish an employee whistle-blower who tells Congress about possible wrongdoing.
Bush's signing statement: The president or his appointees will determine whether employees of the Department of Energy and the Nuclear Regulatory Commission can give information to Congress.
Same as above...nuclear secrets.
QUOTE
Dec. 23, 2004: Forbids US troops in Colombia from participating in any combat against rebels, except in cases of self-defense. Caps the number of US troops allowed in Colombia at 800.
Bush's signing statement: Only the president, as commander in chief, can place restrictions on the use of US armed forces, so the executive branch will construe the law ''as advisory in nature."
A ridiculous resolution. The President is Commander in Chief and how many people think that troop actions should be limited by Congress?
QUOTE
Dec. 17: The new national intelligence director shall recruit and train women and minorities to be spies, analysts, and translators in order to ensure diversity in the intelligence community.
Bush's signing statement: The executive branch shall construe the law in a manner consistent with a constitutional clause guaranteeing ''equal protection" for all. (In 2003, the Bush administration argued against race-conscious affirmative-action programs in a Supreme Court case. The court rejected Bush's view.)
Congress mandates quotas?

Certainly EEOC guidelines, but why specifically instruct one Executive branch official as to what his hiring practices should be?
QUOTE
Oct. 29: Defense Department personnel are prohibited from interfering with the ability of military lawyers to give independent legal advice to their commanders.
Bush's signing statement: All military attorneys are bound to follow legal conclusions reached by the administration's lawyers in the Justice Department and the Pentagon when giving advice to their commanders.
QUOTE
Nov. 5, 2002: Creates an Institute of Education Sciences whose director may conduct and publish research ''without the approval of the secretary [of education] or any other office of the department."
Bush's signing statement: The president has the power to control the actions of all executive branch officials, so ''the director of the Institute of Education Sciences shall [be] subject to the supervision and direction of the secretary of education."
This one should be obvious.
Bush is using these signing statements to advise Congress against attempts to breach the Separation of powers in almost every instance. These examples fall within a few categories: national security, foreign policy, military conduct, and executive branch administration all of which are the responsibility of the President and not Congress.
