11th Cir. Pattern Jury Instr. (Criminal) O58.1

18 U.S.C. § 1503

It’s a Federal crime to try to influence, obstruct, or impede the due

administration of justice [corruptly] [by threats or force] [by any threatening letter

or communication].

The Defendant can be found guilty of this crime only if all the following

facts are proved beyond a reasonable doubt:

(1) there was a proceeding before [this Court] [a United States

Magistrate Judge of this Court] [a grand jury of this Court]; and

(2) the Defendant [by threats or force] [by a threatening letter or

communication] knowingly tried to influence, obstruct, or impede

the due administration of justice in that [judicial] [grand jury]

proceeding.

OR

(2) the Defendant knowingly and corruptly tried to influence, obstruct,

or impede the due administration of justice in that [judicial] [grand

jury] proceeding.

To “influence, obstruct, or impede the due administration of justice” is to do

something to sway or change or prevent any action likely to be taken in the

[judicial] [grand jury] proceeding.

[To act “corruptly” means to act voluntarily, deliberately, and dishonestly

with the specific intent to sway, change, or prevent some action likely to be taken

in the [judicial] [grand jury] proceeding].

The Government does not have to prove that the [judicial] [grand jury]

proceeding was in fact influenced or obstructed or impeded in any way. It only has

to prove that the Defendant [corruptly] tried to influence, obstruct, or impede the

due administration of justice [by threats of force] [by a threatening letter or

communication], and that the natural and probable effect of the Defendant’s acts

would be to sway, change, or prevent some action likely to be taken in the

[judicial] [grand jury] proceeding.
