Osvaldo Jaldo's possible 2027 reelection has moved from party politics into constitutional litigation. Four opposition parties asked the national Supreme Court to challenge Article 90 of Tucumán's constitution, arguing that its wording allows excessive accumulation of terms within the executive ticket. The government replies that Jaldo is serving his first term as governor and remains entitled to reelection.
The dispute centers on how governor and lieutenant-governor terms are counted. Article 90 allows one consecutive reelection, but opponents say Jaldo's earlier service as deputy governor must count toward the limit. The government argues that serving as lieutenant governor does not exhaust the right to a reelection as governor.
The controversy has an immediate precedent. Juan Manzur tried to run for lieutenant governor in 2023 after terms as both deputy and governor, and the courts blocked the ticket. Both sides use that case differently: opponents see a limit on continuity, while Jaldo's supporters say the legal circumstances are not identical.
The Supreme Court filing seeks a ruling before any candidacy is formally registered. Plaintiffs say waiting until list deadlines could create late electoral chaos. Government figures reply that the challenge is abstract because Jaldo is not yet a candidate. That procedural issue may be the court's first test.
The case triggered clashes among mayors, legislators and party leaders. Government figures accuse opponents of trying to win in court what they cannot win at the polls. Opponents answer that constitutional rules exist precisely to limit power and must be enforced before competition begins.
Article 90 also raises a broader institutional question: how long one person may remain in the executive by alternating positions. Plaintiffs argue that the wording could allow up to sixteen years of continuous presence. The government replies that governor and lieutenant governor are distinct constitutional offices.
The Supreme Court's decision will reshape the entire provincial field. If Jaldo is eligible, the ruling coalition can organize around an incumbent governor with territorial machinery. If he is barred, Peronism must resolve a rapid succession and the opposition will reconfigure alliances. Delay itself could also affect calendars.
The next step is whether the Court accepts the case and, if so, how it interprets Article 90. An early ruling would provide predictability; a late one would increase tension. Beyond Jaldo, the decision will establish a precedent on alternation, reelection and succession between the two top provincial offices.
