The Ohio Supreme Court ruled on September 1, 2026, that the Trenton City Council must certify a petition for a charter amendment that would prohibit the construction of data centers in the city. This decision affects the residents of Trenton who are concerned about the potential impacts of data centers on their community. The case underscores the importance of local governance and the legal processes that allow citizens to propose changes to their municipal charters.

The case, known as State ex rel. Blankenship v. Trenton City Council, was filed under docket number 2026-1035. It arose after a group of residents, led by Barry Blankenship and others, submitted a petition to the Trenton City Council seeking to amend the city charter. The proposed amendment aimed to prevent the construction of data centers in Trenton, reflecting the residents' desire to control the development in their community.

The dispute began when the Trenton City Council refused to certify the petition, claiming it did not contain enough valid signatures. The council argued that the petition required signatures from ten percent of all eligible voters based on the total number of registered voters, rather than the total number of votes cast in the last election. This interpretation led to the council's conclusion that the petition fell short of the necessary signatures.

In response, the residents sought a writ of mandamus, asking the court to compel the city council to certify their petition for the upcoming November 2026 general election. The residents argued that the correct interpretation of the law required only ten percent of the votes cast in the previous election, which would mean they had more than enough valid signatures to qualify for the ballot.

The Ohio Supreme Court's ruling clarified the legal requirements for charter amendment petitions. The court stated, "Relators are entitled to a limited writ of mandamus ordering the council to pass an ordinance certifying the petition to the board of elections for submission of the proposed charter amendment to electors at a special election within the time frame stated in Article XVIII, Section 8 of the Ohio Constitution." This decision emphasized that the council had a constitutional duty to submit the proposed amendment to the voters.

The ruling was issued by a per curiam opinion, meaning it was not attributed to a single judge but rather represented the consensus of the court. Chief Justice Maureen O'Connor and Justices Jennifer Brunner, Melody Stewart, and others joined in the decision. Justices Pat Fischer and Sharon Kennedy concurred in part, agreeing with the judgment but not all aspects of the opinion.

The court's decision has significant implications for the residents of Trenton and similar cases across Ohio. By affirming that the number of signatures required for a charter amendment is based on the votes cast in the previous election, the ruling sets a precedent that could influence how local governments interpret signature requirements for future initiatives. This ruling reinforces the principle that local citizens have a right to propose changes to their governance and that city councils must adhere to constitutional guidelines when evaluating such proposals.

Looking ahead, the ruling allows the residents of Trenton to move forward with their proposed charter amendment. The city council must now act to certify the petition and ensure it is placed on the ballot for the upcoming special election. This case may also prompt other municipalities to review their charter amendment processes and ensure compliance with the Ohio Constitution.

Details were not available regarding whether the Trenton City Council plans to appeal this decision or if any related cases are pending. However, the ruling highlights the ongoing legal discussions about local governance and the rights of citizens to influence their municipal laws.
