Which issue regarding substance in administrative agencies involves rules?

The issue involving rules in administrative agencies that pertains to substance is best captured by the concern that rules overlap and conflict. Administrative agencies operate under the authority granted to them by legislatures, allowing them to create rules and regulations within their specific domains. However, one of the challenges is that these agencies may operate independently and may not coordinate effectively with one another. As a result, their rules can sometimes overlap or contradict each other, creating confusion and inefficiency for those required to comply with these regulations.

When rules conflict, it complicates enforcement and compliance for individuals and businesses, as it may not be clear which rule takes precedence. This issue can lead to legal disputes and regulatory uncertainty, as affected parties may struggle to navigate the conflicting requirements. The need for clarity and consistency in regulatory frameworks is essential for fostering a predictable environment for stakeholders.

In contrast, the other options—concerns about rules being too lenient, too easy to understand, or requiring regular revisions—address different aspects of administrative rulemaking but do not capture the complexity and significant challenges posed by overlapping and conflicting regulations. Thus, the issue of overlapping and conflicting rules provides a thorough understanding of the procedural and substantive concerns faced by administrative agencies.
