Overt Act Requirement
Conspiracy — overt act
The rule
Common-law conspiracy was complete on agreement; most statutes require an overt act by any conspirator — even trivial preparation — while some retain agreement-only liability for serious crimes.
In plain English
In conspiracy law, an overt act is a step taken by any member of the conspiracy to further the criminal plan. This means that simply agreeing to commit a crime isn't enough; there must be some action, even if minor, that shows the conspiracy is moving forward.
Worked example
Alice and Bob agree to rob a bank. To further their plan, Alice buys a mask and gloves. Even though they haven't committed the robbery yet, Alice's purchase of the mask constitutes an overt act, making the conspiracy charge valid.
Memory hook
Conspiracy needs a plan and a push — an overt act gets the ball rolling!
The trap
Exams may present scenarios where students focus solely on the agreement and overlook the necessity of an overt act, leading to incorrect conclusions about liability.
How examiners test it
Questions often involve fact patterns where students must identify whether an overt act has been committed, sometimes disguising it within a larger narrative about the conspiracy.
