A Rotterdam court said it would rule April 7 on a petition by the Dutch Islamic Federation seeking to gag Wilders and order him to publicly apologize.
Wilders' lawyer Serge Vlaar said the federation "wants to ban a point of view," which he said was not possible under Dutch law.
Federation lawyer Ejder Kose countered that "my clients are not attacking freedom of speech. This is about ending the unjustified insulting of Islam."
Outside the courtroom, a pro-Wilders demonstrator shouted far-right slogans until police removed him.
15-minute film — titled "Fitna," or "Strife" in Arabic — was made by anti-immigrant lawmaker Geert Wilders and was posted on a Web site Thursday.
HOST SITE REMOVED THE FILM
The host site, LiveLeak.com, removed the film Friday evening, citing threats to its staff "of a very serious nature." But the film already had been widely dispersed across the Internet on file-sharing sites.
Employing elements and symbols calculated to offend Muslims, it draws on recycled footage of terrorist attacks and anti-Western, anti-Jewish rhetoric meant to alarm the native Dutch.
