Cardano’s governance framework is approaching a Sept. 1 deadline that could effectively stall most major on-chain governance if a vote to renew four Constitutional Committee seats fails.
Four of the committee’s seven seats expire at epoch 653. If the renewal does not pass, only three members will remain, below Cardano’s minimum committee size of five.
Intersect warned on Aug. 14 that such an outcome would leave only Info Actions and Update Committee actions available until the committee is restored above the minimum. The blockchain itself would continue processing transactions and producing blocks normally.
The renewal was submitted on-chain July 31 after Cardano completed and independently audited its 2026 Constitutional Committee election.
The four elected candidates are ready to take their seats, but DReps and stake pool operators, or SPOs, must still approve the on-chain action. The existing Constitutional Committee does not vote on its own renewal.
Voting remains far below the required thresholds
A live Aug. 17 GovTool snapshot showed the renewal with 32.46% support from delegated representatives, or DReps, and 1.95% from SPOs. It needs 67% and 51%, respectively.
That represents some progress from Intersect’s Aug. 14 snapshot, when DRep support stood at about 30% and SPO backing at 1.69%, but both remain well short of passage. Intersect confirmed that the action expires Sept. 1 at epoch 653.
Enough uncast voting power remains for both thresholds to be reached. Using the live voting buckets and holding the displayed denominators static, DReps would need roughly another ₳1.53 billion in support, while SPOs would need about ₳5.21 billion.
The remaining stake makes passage possible, not probable. Delegations can change, and uncast voting power does not necessarily translate into eventual support.
There is also a separate timing constraint.
The incoming members would receive terms ending at epoch 799. Cardano’s committeeMaxTermLength is 146 epochs, exactly the distance between epochs 653 and 799.
That means the update cannot be enacted earlier while preserving those expiration dates because doing so would produce terms longer than the protocol permits.
The proposal itself says the four seats expiring at epoch 653 are being replaced with candidates elected through the 2026 process, with the new terms ending at epoch 799.
Failure would stall most Cardano governance
Intersect said failure would reduce the committee from seven members to three, below the committeeMinSize requirement of five, and “effectively stall” Cardano governance until enough members are restored.
The five-member floor is relatively new. Cardano previously required all seven committee seats to be active, but a governance action reducing committeeMinSize from seven to five was ratified in July to provide a buffer against resignations, expirations, or other vacancies.
Losing four seats at once would exhaust that buffer.
Intersect’s latest guidance says only Info Actions and Update Committee actions would remain available while the committee is undersized.
That would prevent governance from progressing on areas including hard forks, protocol-parameter changes, constitutional changes, and treasury withdrawals until an Update Committee action restores enough members.
The Sept. 1 deadline therefore does not threaten Cardano’s operation as a blockchain. It threatens the network’s ability to make most consequential on-chain governance decisions until its Constitutional Committee is rebuilt.
