Which of the following actions may result in liability under Section 546C of the Crimes Act?

Liability under Section 546C of the Crimes Act is primarily concerned with actions that obstruct law enforcement officers in the performance of their official duties. Hindering police in the execution of their duties directly aligns with this provision, as it encompasses a range of behaviors that could impede or interfere with the lawful exercise of police powers.

When individuals hinder police officers, they may disrupt investigations, prevent officers from carrying out lawful orders, or otherwise obstruct the duties that officers are legally permitted to perform. This can lead to significant repercussions, both for public safety and for the effectiveness of law enforcement agencies.

In contrast, the other options involve actions that do not inherently reflect a hindrance to police duties under the specific legal framework of Section 546C. For instance, resisting a civil officer or defending oneself against police may occur under different circumstances and often involve a legal discussion of rights, such as self-defense or unlawful detention, whereas assisting a police officer clearly does not align with actions that would constitute hindrance. This context helps clarify why hindering police execution of duty is the action that attracts liability under the section in question.
