Not everything is a department
Distinguish departments, public corporations, bureaus, and boards.
Names offer clues; laws determine powers
A department often combines policy and administration. A bureau can be a specialized component. A public corporation has the legal identity and powers established in its statute. A board can govern an entity, regulate an activity, or decide disputes. These labels are clues, not substitutes for the governing legislation.
Operating is different from regulating
The institution delivering a service can differ from the one regulating the sector. Public health insurance administration is also different from running a hospital. ASES administers contracting for government health insurance; that does not make it the administrator of every health facility.
Structures change
In 2025, Act 83 established an autonomous Puerto Rico Police and replaced the former bureau attached to Public Safety. A directory retaining the old name may be useful historically but cannot establish the present reporting relationship. Historical profiles help readers recognize older names without counting them as additional active institutions.
Service integration and legal merger
ATI describes a transportation system that includes rail, buses, and maritime services. Act 123-2014 authorizes a merger of AMA and ATM subject to conditions. That authorization alone does not establish that the merger was completed. Service coordination, administrative attachment, and legal identity are different questions.
ATI: about the authority and Act 123-2014, art. 17(d). Sources checked October 18, 2026.
Compare ATI, AMA, and ATM. The profiles distinguish service integration from the merger whose implementation remains unverified.
Check your understanding: Does an institution’s name establish all its powers?
No. Its enabling law and current provisions establish its authority.
