The Oklahoma Jury Instruction — 2.2.4.2, also known as "Pretrial Detainee Alleging Deliberate Indifference to Serious Medical Need," is a legal guideline designed to provide specific instructions to jurors in cases where a pretrial detainee has accused officials of deliberate indifference towards their serious medical needs. This instruction aims to ensure that jurors understand the legal standards and considerations involved in such cases. Under this instruction, the jury is instructed to carefully evaluate the evidence and circumstances presented in the case. It specifically directs the jury's attention to the detainee's claim of having a serious medical need and whether the officials involved demonstrated deliberate indifference towards addressing that need. The instruction emphasizes that, in order for the detainee to prevail in their claim, they must establish two key elements: first, that they had a serious medical need, which is defined as a condition that is both objectively serious (i.e., a condition that a reasonable person would find significant) and verified by medical professionals; and second, that the officials were deliberately indifferent to addressing the detainee's medical need. The instruction further guides the jury in determining deliberate indifference. It explains that deliberate indifference exists when officials have actual knowledge of a serious medical need and consciously disregard that need, displaying deliberate or callous indifference towards the detainee's well-being. The jury is advised to evaluate the reasonableness of the officials' actions or lack thereof, taking into account the available resources, the detainee's medical history, and any other relevant factors. The instruction may also include variations or modifications depending on the specific circumstances of the case. This ensures that the jury considers any unique aspects and applicable laws related to the detainee's claim of deliberate indifference towards their serious medical need. Overall, Oklahoma Jury Instruction — 2.2.4.2 is a crucial tool in guiding the decision-making process for juries in pretrial detainee cases involving allegations of deliberate indifference towards serious medical needs. By providing clear guidelines and outlining the key elements of such claims, the instruction promotes fairness, consistency, and an understanding of the legal standards involved in these cases.
