Learning Objectives

Analyze complex multi-defendant conspiracies: chain (drug distribution) vs. wheel (hub-and-spoke) structures
Apply Wharton's Rule: no conspiracy when the target crime inherently requires the agreed-upon number of participants
Distinguish co-conspirator statements (admissible during and in furtherance of conspiracy) from post-conspiracy statements

Key Rules

Chain conspiracy: Each link is connected to the next; all are part of a single conspiracy if aware of the overall scheme. Wheel conspiracy: Hub connects to spokes; spokes are only co-conspirators if aware of each other and the overall enterprise.
Wharton's Rule: When a crime requires two or more participants (dueling, bribery, adultery), those participants cannot be charged with conspiracy unless more persons than necessary participate.
Conspiracy does NOT merge: Defendant can be convicted of BOTH conspiracy AND the completed target crime.

Conspiracy & Multi-Party Liability

Conspiracy as Extended Liability

Conspiracy is unique: it is both a standalone crime AND a basis for holding each conspirator liable for crimes committed by others.

Pinkerton Liability (Review)

Each conspirator is liable for: 1. The target crime 2. ALL other crimes by co-conspirators that are (a) in furtherance and (b) reasonably foreseeable

Complex Conspiracy Structures

Chain Conspiracy (Drug Distribution)

Supplier → Distributor → Street Dealer - Each link connects to the next - All part of ONE conspiracy if each knows they're part of a larger operation

Wheel (Hub-and-Spoke)

Hub (organizer) → Spoke 1, Spoke 2, Spoke 3 - Spokes are co-conspirators with the hub - Spokes are co-conspirators WITH EACH OTHER only if aware of the overall enterprise

Baby Bar Connection

Conspiracy + Pinkerton + felony murder creates maximum liability in multi-defendant criminal law essays. The examiners frequently combine these doctrines to test whether you can trace liability through multiple theories.

Cases to Know

Pinkerton v. United States (1946) — vicarious liability for co-conspirator crimes
Kotteakos v. United States (1946) — wheel conspiracy; spokes are not co-conspirators with each other absent knowledge of overall scheme

Baby Bar Relevance

Conspiracy + Pinkerton is a Baby Bar favorite for multi-defendant essays. It often combines with felony murder for maximum liability analysis.
