According to LEPRA Section 203, when is a warning required?

In the context of LEPRA Section 203, a warning is required from police officers when a person does not comply with a request made under the legislation. The rationale behind this is to ensure that the individual is informed of their rights and the consequences of non-compliance. The emphasis on issuing a warning only if there is a lack of compliance serves to protect both the individual's rights and the integrity of the law enforcement process, allowing individuals to fully understand their obligations during interactions with police.

The other options suggest circumstances that are not stipulated within the section as requiring a warning. For example, always requiring a warning before making requests or when two officers are present does not align with the specific legal text. The notion of a warning being necessary prior to conducting a search is also not mentioned in this context, making it clear that the focus is on compliance and the subsequent actions that follow a person's refusal.
