The plan is contradictory, because it seeks to naturalize people who were already born in the Dominican Republic and do not have passports from another country, according to Joseph Cherubin, director of the local nonprofit Sociocultural Movement for Haitian Workers.
"To naturalize someone, they need to have a foreign passport," he said. "You can't naturalize a Dominican."
The plan is being launched as 464 people have either been deported to Haiti or left the Dominican Republic voluntarily in the past week due to anti-Haitian sentiments following the murder of an elderly Dominican couple.
Dominican and Haitian officials were scheduled to discuss the court ruling on Saturday, but the Dominican government canceled the meeting after the Caribbean Community criticized the ruling and said it would defer a Dominican request to become a member of the trade bloc.
Dominican Presidential Minister Gustavo Montalvo had said the government felt Haiti violated an earlier agreement to prioritize bilateral dialogue in the case.
