On 20 January, the newspaper Dziennik reported that Mr Waltz's documents had been two days past the deadline, which in his case had been on 28 December 2006.

Based on this, Prime Minister Jarosław Kaczyński of the governing Law and Justice (PiS) party maintained that Gronkiewicz-Waltz's mandate had expired on 28 December 2006, and announced that the local elections would be repeated.

Gronkiewicz-Waltz's party Civic Platform argued that the prime minister did not have the authority to make this decision, and that the case would need to be examined in court instead.

Polish legal experts maintained that by submitting their statements on the same day, Gronkiewicz-Waltz had observed the spirit, if not the letter of the law.

Though equality marches have been officially allowed in the past, they had always met with strong resistance during the term of Lech Kaczyński as Mayor of Warsaw, particularly from the All-Polish Youth movement.
