I have a couple of questions about Executive Orders . . .

[OneBlueSky]

do they carry the force of law? . . . if so, from where do they derive their legitimacy? . . .

yesterday, someone posted something about Executive Orders becoming law if the Congress doesn't overturn them within a specified amount of time (I think 30 days was mentioned) . . . is this true? . . . does Congress have the power to do that? . . .

if EOs DO become law after a given time, does that mean that the one giving the president dictatorial powers in times of national emergency is now the law of the land? . . . and if that's the case, why didn't Congress challenge it? . . . is there still time to challenge it? . . .

any info (or links) you might have about Executive Orders and how they work would be appreciated . . . thanx . . . :)
