From the viewpoint of the People's Party (PP), the Democratic Memory Law or 'Grandchildren Law' has caused serious problems in Spain's consular network, overwhelming available resources and leading to processing delays. The PP claims the government lacked adequate planning for this influx and criticizes the law as an electoral strategy to augment the Socialist party's voter base unfairly. Outcry from the Spanish Association of Diplomats (ADE) supports the need for transparency and improved procedural guidance to handle new citizenship registrations. These challenges emphasize the strain on consulates, with some consulates facing a backlog that could take decades to clear.
The PP and allied parties such as Vox have challenged the law legally, contending it disrupts electoral balance and burdens diplomatic services. They advocate for suspending or revising the law until implementation issues are resolved and consular services can adequately keep pace with demand.
