Displeased with a Texas appeals court's decision to allow a legal bid to dismantle the city's comprehensive plan to continue, the city of Plano is turning to the state's highest civil court for another opinion.

The city of Plano on Monday filed a petition with the Supreme Court of Texas to review a February decision from the state's Fifth District Court of Appeals. At issue in the lawsuit is whether the city secretary is obligated to submit a petition for a referendum on the city's comprehensive plan to Plano City Council.

The city has argued its comprehensive development plan cannot be put before the voters given the complex nature of the plan, the expertise needed to formulate it and the requirement that specific procedures be followed before one is adopted.

The appeals court ruling in question had left open a portion of the legal challenge that would require the city secretary to present a referendum on the strategic plan to the council.

Jack Ternan, an attorney for the group suing the city, did not say whether his clients planned to file an appeal of their own to the Supreme Court. In the same February ruling, the appeals court had dismissed some of the group's claims against the city for lack of jurisdiction. One of these dismissed claims asked the courts to require officials to suspend the Plano Tomorrow plan, readopt the city’s 1986 strategic plan and call a special election.

"We are disappointed that the city secretary has chosen to file another appeal rather than comply with the city charter and prior court rulings and are evaluating our options," Ternan said in a statement Wednesday.
