Being approved on a reserve list does not, by itself, create an immediate right to appointment. As a general rule, candidates ranked outside the number of vacancies stated in the notice have an expectation of appointment. The situation can change when concrete facts move the candidate into the originally offered vacancies or when arbitrary and unjustified preterition is clearly proven.
The key is to separate three questions: how many vacancies the notice offered, the candidate's effective position while the exam remains valid, and whether the Administration acted in a way that shows an unequivocal need to appoint while ignoring the ranking or excluding approved candidates without adequate justification.
General rule: a reserve list is an expectation, not an automatic appointment
In Theme 784, Brazil's Federal Supreme Court held that new vacancies or the opening of a new exam for the same position during the validity of the previous exam do not automatically create a right to appointment for candidates ranked outside the announced vacancies. A legally relevant event, especially arbitrary and unjustified preterition, must be proven.
Scenario guide
| Scenario | Practical rule | What must be shown |
|---|---|---|
| Approved within the number of vacancies in the notice | There is a subjective right to appointment under STF Theme 161. | Final ranking, number of vacancies and validity period. Extremely exceptional circumstances may justify non-appointment only if they are supervening, unforeseeable, serious, necessary and duly reasoned. |
| Approved only on the reserve list | As a rule, there is only an expectation of appointment. | Approval alone is not enough. A later event capable of changing the legal position must be identified. |
| Withdrawal, resignation, disqualification or absence of a better-ranked candidate | A right may arise when, during the validity period, the event moves the candidate into the number of vacancies originally offered. | Official calls, withdrawal or resignation acts, disqualification records and the candidate's updated ranking. |
| New vacancy arises | This does not automatically create a right for reserve-list candidates. | Beyond the vacancy itself, there must be evidence of an unequivocal need to appoint during the validity period and arbitrary preterition. |
| New exam for the same position | This also does not automatically create a right for candidates on the previous reserve list. | The earlier exam's validity, constitutional priority and any concrete preterition must be examined. |
| Ranking order is ignored | Preterition caused by breaking the ranking order may create a right to appointment. | Compare the official ranking with published appointment and call acts. |
| Temporary or precarious hiring | By itself, it is not enough to prove preterition. Context is decisive. | The hiring must be connected to the same position or duties, with facts showing a permanent staffing need and arbitrary exclusion of approved candidates during the exam's validity. |
When withdrawals change a reserve-list candidate's position
Withdrawals by better-ranked candidates can change the legal situation of someone initially outside the vacancies. STJ case law recognizes that if withdrawals or equivalent events occur during the exam's validity and move a candidate into the number of vacancies originally offered, the expectation can become a subjective right to appointment.
New vacancies and a new exam: why they are not enough by themselves
STF Theme 784 rejects an automatic conclusion. A vacancy that appears after the notice may show room in the staffing table, but it does not by itself mean that every reserve-list candidate must be appointed. The same applies to a new exam opened while the previous one remains valid.
The candidate must clearly prove that the Administration revealed an unequivocal need to appoint during the validity period and nonetheless arbitrarily and unjustifiably preterited approved candidates. Article 37, IV, of the Constitution also provides priority for candidates from a still-valid exam over newly approved candidates for the same career, but the concrete result depends on the facts and the candidate's position.
Temporary hiring requires context
Simplified answers often fail here. Some precedents have treated precarious hiring during the validity of an exam as relevant evidence of preterition. In 2025, however, the STF emphasized that temporary hiring does not, by itself, establish arbitrary and unjustified preterition.
The candidate should therefore gather evidence about whether temporary workers perform the same duties as the permanent position, whether the need is permanent, how many contracts were made, how long they lasted, when they occurred and whether approved candidates were left aside despite an apparent staffing need.
Documents that help verify the claim
- the opening notice and amendments, including vacancies by position, location, specialty and competition category;
- the final result and official ranking;
- the homologation act, validity period and any extension;
- official gazettes with appointments, calls, withdrawals, resignations, eliminations or disqualifications;
- acts creating or vacating positions when the argument involves new vacancies;
- the notice for a new exam for the same position, if any;
- temporary contracts, simplified selection procedures or other acts used to support a preterition claim;
- administrative requests and the agency's responses, when available.
Conclusion
Candidates approved within the number of vacancies stated in the notice generally have a subjective right to appointment. Candidates on a reserve list start with an expectation. That expectation can become a right in specific circumstances, such as withdrawals during the validity period that move the candidate into the original vacancies or proven arbitrary and unjustified preterition under the applicable case law.
