Final answer:
The rule's maintenance requirement ensures ongoing review of covered entities' actions for reasonableness and appropriateness, preventing discrimination or unfair treatment.
Step-by-step explanation:
The rule's maintenance requirement provides that a continuing review of the reasonableness and appropriateness of a covered entity's or BA's (or subcontractor's) actions is necessary. This requirement ensures that the entity or individual is acting within the parameters of the law and maintaining compliance. It helps to prevent any potential discrimination or unfair treatment.
For example, in the context of the rational basis test, this requirement would ensure that a covered entity or individual is not engaging in discriminatory practices without a good reason. The burden of proof would be on those challenging the entity's actions to demonstrate that there is no valid justification for treating them differently.
