Some prominent examples of the next in rank rule in practice:
1. Monarchies: In constitutional monarchies like the United Kingdom, the successor to the throne typically follows a clear line of succession established by law, usually based on primogeniture (where elder children have precedence) and male precedence (where males come before women).
2. Presidential systems: Many presidential systems have a clear line of succession in case the president becomes unable to serve. For instance, in the United States, the Vice President assumes the presidency if the President dies, resigns, or is removed from office.
3. Corporate governance: In business organizations, the next in rank rule may apply to executive positions or leadership roles. When the current CEO or managing director leaves, the company may appoint the most senior or suitable person from within the organization as the successor.
4. Sports teams: In sports, if the captain of a team is unavailable, the next in rank, typically the vice-captain or a senior player, may take over the captaincy duties.
The next in rank rule provides stability, predictability, and continuity when leadership positions need to be filled. It helps ensure that there is a smooth transition of power and that decision-making is not disrupted. However, the specific rules and criteria for succession may vary depending on the organization or entity in question.
