Judge rules that couple can't name their baby "Friday"

Normally, I'm against giving a baby a weird name because school is hard enough, why give them a name that will be snickered at during attendance? In this case I think the name is not as outrageous as it could have been (such as "@") and I think the court overstep its bounds by forcing the couple to name the kid Gregorio:

What's in a name? If the name is Friday, shame and ridicule, according to Italian judges who forbade a couple from naming their child like the character in "Robinson Crusoe."

"They thought that it recalled the figure of a savage, thus creating a sense of inferiority and failing to guarantee the boy the necessary decorum," the couple's lawyer, Paola Rossi, said Wednesday.

[...]

"They wanted an unusual name, something original, and it did not seem like a shameful name," Rossi said in a telephone interview. "We think it calls to mind the day of the week rather than the novel's character."

Since city hall officials are obliged by law to report odd names, the matter ended up before judges in Genoa, the northern Italian city where the couple live.

Rossi said the court, which upheld a previous ruling made in June, also ordered the boy to be named Gregorio after the saint on whose day he was born.

What right does a court have to force a name upon their child? Sheesh! Naming a child is the prerogative of the parents. I wonder if they have to do it? What if they were Protestant or atheists?
