Update Constitutional Committee ratified under Cardano governance

Cardano’s Constitutional Committee just got a refresh. The “Update Constitutional Committee 2026” governance action was ratified on-chain, seating four newly elected members and preserving the network’s ability to make critical governance decisions during a period of significant upcoming upgrades.

The vote cleared its two required thresholds with little room to spare. Delegated Representatives (DReps) approved the action at 69.36%, edging past the 67% requirement. Stake Pool Operators (SPOs) came in at 51.18%, barely above the 51% needed. In a system where non-voting stake effectively counts against approval, those margins tell a story about just how contested governance participation remains on Cardano.

What the Constitutional Committee actually does

Under the Voltaire era governance model, the CC reviews governance actions to ensure they align with the network’s constitution before they can take effect. Without a functioning committee of sufficient size, the network loses the ability to execute treasury withdrawals, adjust protocol parameters, and approve other foundational changes.

Had this ratification failed, the committee would have shrunk to just three members, essentially creating a governance bottleneck at the worst possible time. The governance action was submitted on-chain on July 31, 2026, and ratification occurred around September 1. The transition becomes effective at the boundary of Epoch 653 to Epoch 654, which lands on September 6, 2026. The four newly elected members, chosen through audited community elections, will serve terms extending to Epoch 799.

Who sits on the new committee

The renewed committee includes representatives from several corners of the Cardano ecosystem. Among the newly seated members are Marek Mahut, the Eastern Cardano Council, and Cardano Curia.

Cardano is preparing for two major protocol milestones: the Leios upgrade and the Dijkstra era. Both will require governance actions that pass through the Constitutional Committee’s review process.

Why the margins matter

A 69.36% DRep approval rate against a 67% threshold means roughly 2.36 percentage points separated success from failure. On the SPO side, the gap was even thinner at 0.18 percentage points above the minimum.

Cardano’s governance design includes a feature that amplifies this dynamic: stake that doesn’t vote effectively functions as opposition. If a large holder sits out, their abstention drags down the approval percentage. This means governance outcomes depend not just on who votes yes or no, but on overall participation rates.
