Route decision for road widening near Amelisweerd annulled
The Administrative Law Division has annulled the route decision ‘A27/A12 Ring Utrecht’ for the widening of the national roads A12, A27, and A28 near Amelisweerd. The Minister of Infrastructure and Water Management has failed to rectify the deficiencies in this decision. In an interim ruling (opens in new window) (links to an external website) from April 2025, the Administrative Law Division had already urged the Minister to better motivate whether the requirements for external offsetting of nitrogen were met. However, this has not been successful. This is evident from a ruling by the Administrative Law Division today (March 11, 2026). With this, the widening of the national roads A12, A27, and A28 as envisaged by the Minister with this route decision, is off the table.
Interim ruling assignment
In the interim ruling, the Administrative Law Division urged the Minister to better motivate whether the cancellation (external offsetting) of the nitrogen increase from the road project against a nitrogen decrease due to the cessation of several agricultural businesses, met the conditions that apply to this. One of these conditions is the additionality requirement.
Deficiency not rectified
The Administrative Law Division is of the opinion that the Minister has not sufficiently motivated that the additionality requirement is met. Thus, the deficiency in the route decision has not been rectified.
Additionality requirement
The road project has negative consequences for five Natura 2000 areas around the Ring Utrecht: Veluwe, Binnenveld, Oostelijke Vechtplassen, Naardermeer, and Nieuwkoopse Plassen & De Haeck. The majority of these Natura 2000 areas are overloaded with nitrogen. The Minister had to substantiate that the nitrogen decrease from the ceased agricultural businesses is not necessary to prevent impending deterioration of nature in these areas. Nature conservation law requires that it is continually assessed whether the measures to reduce the amount of nitrogen in these areas still suffice or whether more or different measures are needed. The Minister should therefore have based his rectification decision on the most recent information about the state of nature in these natural areas. This information is in the nature target analyses and the advice thereon from the Ecological Authority. The Minister has not included these analyses and advice in his rectification decision, but he should have. These analyses show that the state of nature in these areas is insufficient. Therefore, the Minister cannot now claim that the desired nitrogen reduction can be achieved with only the existing measures and that the nitrogen reduction from the ceased agricultural businesses is not also needed.
For the Minister, more than a verification obligation applies
The Minister argued that he could suffice with verifying whether the competent provinces deem the nitrogen reduction from these businesses necessary for the Natura 2000 areas (the so-called verification obligation). The Administrative Law Division does not agree with this. A Minister, unlike a municipal council, indeed has powers to influence the state of nature in Natura 2000 areas.
Extra compensation
Now that the additionality requirement is not met, the Minister was not allowed to use external offsetting to make the road project possible. But external offsetting was not the only option. The Administrative Law Division had already pointed out to the Minister in the interim ruling that, instead of external offsetting in the rectification decision, he could also choose extra compensatory measures to compensate for the loss of nature (quality). The Minister has not made use of this.
Consequence of the ruling
Now that the deficiencies in the route decision have not been rectified, the Administrative Law Division has annulled the route decision 2020 and the amended route decisions from 2022 and 2025. With this, the widening of the national roads A12, A27, and A28 as envisaged by the Minister with this route decision, is off the table.
