The Ombud Act provides authority to investigate which type of complaints?

The Ombud Act is designed specifically to address complaints related to administrative actions and decisions made by public bodies or government entities. This means that the Ombudsman has the authority to investigate issues where individuals believe they have been treated unfairly or inequitably by governmental processes, including issues of maladministration, poor service, or violations of rights within the public system.

In contrast, the other types of complaints listed do not fall within this jurisdiction. Criminal nature complaints typically fall under law enforcement and the judicial system, private sector complaints would be handled by consumer protection agencies or other regulatory bodies, and family law complaints are addressed through specific family courts and legal frameworks dedicated to those issues. Therefore, administrative nature complaints are the correct focus for the Ombudsman under the Ombud Act, as this aligns with their mandate to ensure fairness in public administration.
