Multiple Conspiracy Defendants
The government indicted six defendants on overlapping but distinct conspiracy counts arising from separate loan schemes. Michael Miller moved to sever his trial, arguing the evidence against the other five would spill over and confuse the jury. The court granted the motion because the proof of each scheme was readily separable and joint trial would prejudice Miller's defense.

Robbery Codefendant Trial

Conspiracy Severance Request

Informant Codefendant Motion

Frequently Asked2
When does a court grant a motion to sever defendants?+
A court grants severance when joinder would cause substantial prejudice that cannot be cured by limiting instructions. The moving party must show that the risk of prejudice outweighs the efficiency of a joint trial.
What showing is required to sever charges under Rule 14?+
The defendant must demonstrate that joinder would prevent a fair trial. Courts weigh the risk of prejudice against judicial economy and may order severance or other protective measures.

Joint Tenant Lease Dispute
Mohan Malhotra and Marcus Mitchell held Blackacre as joint tenants. Mohan executed a three-year lease of his interest to a third party. Marcus filed a motion to sever the tenancy, claiming the lease broke the unity of title. The court denied the motion after finding that the lease created only a cotenancy for its term without extinguishing the right of survivorship.
Frequently Asked1
Does a lease by one joint tenant automatically sever the tenancy?+
No. Under the modern approach the lease creates only a cotenancy for its duration. The surviving joint tenant takes free of the lease if the leasing tenant dies first.
