LLB Criminal Law - Practice Paper 5

Anna and Brian are environmental activists who plan to sabotage a chemical plant they believe is illegally dumping toxic waste into a river. Their plan involves breaking into the plant at night and opening the main drainage valves to flush the storage tanks with clean water, neutralising the chemicals before they can reach the river. Anna researches the plant layout and identifies a security guard roster showing only one guard, David, will be on duty. Brian obtains specialist tools to open the valves. On the night, Anna cuts the perimeter fence while Brian disables the CCTV system. Inside, they encounter David who challenges them. Anna tells David, "Leave now or we'll lock you in the control room." David refuses to leave and physically blocks their path. Brian pushes David aside, causing David to fall and fracture his hip. Anna and Brian then open the drainage valves but miscalculate the water pressure. The resulting flood causes £500,000 damage to the plant and the discharge of untreated chemicals into the river, killing fish for a two-mile stretch. A nearby resident, Eleanor, drinks contaminated water before the pollution is detected and suffers kidney damage requiring hospitalisation. Discuss the criminal liability of Anna and Brian, considering property offences, non-fatal offences against the person, environmental offences, and any available defences including duress of circumstances and necessity.

The mandatory life sentence for murder is the single greatest obstacle to a coherent and just law of homicide. Critically evaluate this proposition, considering the relationship between the mandatory sentence, the breadth of the mens rea for murder, and the role of partial defences in mitigating its harshness. Would a discretionary sentencing regime for murder improve the law?

Faisal, a taxi driver, picks up a passenger, Gemma, late at night. During the journey, Gemma reveals she is carrying £10,000 in cash to pay a debt owed to a loan shark named Hassan. Gemma says Hassan has threatened to kill her family if she does not pay by midnight. Faisal, sympathising with Gemma, suggests they could split the money and tell Hassan someone robbed them. Gemma agrees. They stage a fake robbery: Faisal stops the car in a dark street, Gemma screams and messes up the car interior, and they divide the £10,000 equally. Gemma then contacts Hassan and tells him she was robbed. Hassan does not believe Gemma and sends his associate, Ivan, to find Faisal. Ivan locates Faisal at his home and threatens him at knifepoint, demanding the money. Faisal, terrified, gives Ivan the £5,000 and also hands over £2,000 of his own savings. Ivan takes the money and also steals Faisal's car. The next day, Faisal reports to the police that he was robbed by Ivan but does not mention the staged robbery with Gemma. Discuss the criminal liability of Faisal, Gemma, Hassan, and Ivan.

Critically evaluate whether English criminal law should adopt a general defence of necessity. Discuss the current position (R v Dudley and Stephens [1884], Re A (Children) [2001], R v Quayle [2005]) and consider arguments from principle, policy, and comparative law.

Kelly is a paramedic who responds to an emergency call at a block of flats. She finds Leo, aged 22, unconscious from a heroin overdose. Kelly administers naloxone, which revives Leo. Leo becomes aggressive and punches Kelly in the face, breaking her cheekbone. Kelly's partner, Michael, another paramedic, restrains Leo by placing him in a chokehold. Leo loses consciousness. Michael releases the hold but Leo does not regain consciousness and is later pronounced dead. A post-mortem reveals Leo had an undiagnosed heart condition which made him vulnerable to cardiac arrest during physical restraint. Michael had no knowledge of this condition. The ambulance service's guidelines state that chokeholds should never be used by paramedic staff. Meanwhile, it emerges that the original 999 call was made by Leo's flatmate, Nina. Nina had watched Leo inject heroin and initially tried to help by slapping his face and throwing cold water on him. When this did not work, Nina considered calling an ambulance but delayed for 20 minutes because she was worried about police attending and finding her own drug supply. By the time paramedics arrived, Leo had suffered oxygen deprivation which contributed to his vulnerability. Discuss the criminal liability of Leo, Michael, and Nina.
