Final answer:
Gonzalo can challenge the IO's decision through an administrative appeal, which involves submitting a written appeal with evidence and arguments to a higher authority within the organization. This allows for reconsideration and the potential reversal of an unjust decision.
Step-by-step explanation:
If Gonzalo wants to challenge the IO's decision, he can do so through a mechanism called an administrative appeal. An administrative appeal is a formal process where an individual or organization challenges a decision made by a government agency or administrative body. In this case, Gonzalo can submit a written appeal to a higher authority within the organization that made the initial decision, outlining the reasons why he believes the decision was incorrect or unfair.
Gonzalo should provide detailed evidence and arguments to support his case. The higher authority will review the appeal, consider the evidence presented, and make a determination on whether to overturn or uphold the original decision. This mechanism allows individuals to seek reconsideration and potentially reverse a decision they believe is unjust.
