In December 2024, the Democratic Unionist Party (DUP) and Ulster Unionist Party (UUP) announced their intention to trigger the Stormont Brake to block the implementation of the Labelling CLP Legislative Act in Northern Ireland (NI). The parties argued that the legislation could significantly disrupt chemical trade flows between Great Britain (GB) and Northern Ireland, valued at approximately £1 billion ($1.25 billion) annually, due to increased regulatory divergence.

What Would the Stormont Brake Have Meant?

If applied, the Stormont Brake would have prevented the CLP Legislative Act from taking effect in NI. The legislation could only have been enforced in NI if the UK-EU Joint Committee reached an agreement. This scenario could have led to Northern Ireland diverging not only from Great Britain but also from the European Union in terms of chemical regulations.

What Is the Stormont Brake?

The Stormont Brake, introduced under the Northern Ireland Protocol, allows NI to block EU legislation from automatically becoming law. This applies if the legislation is deemed to have a “significant impact on everyday life” in the region. The mechanism serves as a last resort and includes strict criteria:

• Objecting politicians must provide a detailed written explanation and prove they exhausted all other mechanisms.
• They must engage in substantive discussions with the UK government and the NI power-sharing government.
• They are required to consult businesses, traders, and civic groups impacted by the legislation.

If the UK Parliament agrees that these conditions have been met, the Stormont Brake is triggered, initiating consultations with the EU-UK Joint Committee.

Outcome of the Stormont Brake Attempt

The UK government had a two-month interim period to assess whether the Stormont Brake criteria were satisfied. On January 20, 2025, the government rejected the application, stating:
“The Brussels Effect means most Great Britain companies will just adopt the EU labelling standard to continue selling into that market. As a result, GB-NI trade issues won’t arise.”

This decision aligns with the UK government’s current strategy to improve relations with the EU.

What This Means for Chemical Regulations in NI

For now, chemical products placed on the market in NI must continue to comply with EU legislative standards, as they have since Brexit came into force. However, this incident demonstrates that the Unionist parties are prepared to use the Stormont Brake mechanism again. Many view this as a test case for the UK government’s willingness to uphold the protocol.
