How does legitimate reliance on a prior agency practice affect subsequent agency actions?

• A. If reliance was reasonable and well-known, a sudden departure could raise legitimate-expectations concerns and require proper notice.
• B. It guarantees the agency must maintain the prior practice.
• C. It has no effect on subsequent actions.
• D. It requires formal rulemaking for changes.

Answer: (A)

When an agency’s prior practice is reasonably relied upon by those it regulates, people act on that expectation. If the agency then suddenly departs from that practice, it can undercut the relying parties’ planning and investments, which raises legitimate-expectations concerns. Because of that, the agency may be required to provide proper notice before changing course, giving affected parties a chance to adjust or respond. This reflects a fairness principle in administrative action: changes shouldn’t surprise those who have reasonably depended on the agency’s established behavior. That’s why this option is best. It captures the idea that reasonable and well-known reliance creates expectations that can constrain abrupt shifts, demanding notice to avoid arbitrary action. It doesn’t guarantee that the prior practice must be kept, and it doesn’t automatically require formal rulemaking in every case; the central point is the protective effect of legitimate expectations and the need for notice when those expectations exist.
