The decision reached by a school in Switzerland's northern municipality of Therwil sought to reach a compromise with two male students, aged 14 and 15, and their families, but ended up causing uproar and fierce public debate over the limits of religious freedom.
"We have asked for an expert opinion from our legal service," said Deborah Murith, spokeswoman for the education department in the canton of Basel-Country, where Therwil is located.
To avoid approving the de facto discrimination of female teachers, the school decided to exempt the boys from shaking hands with any of their teachers, regardless of sex.
That ruling -- made independently by the school without involvement of the cantonal authorities or municipal officials -- triggered an outcry across Switzerland.

Justice Minister Simonetta Sommaruga insisted on Swiss public television yesterday that "shaking hands is part of our culture", in remarks echoed by other senior officials and public figures.
She said the compromise reached by the school could serve as a "provisional measure", while the legal expert prepares guidance, without specifying when that decision would be made.
The head of the Therwil school system, Christine Akeret, told Swiss media that she plans to abide by the expert ruling, but voiced frustration that she had not previously been given instruction from higher authorities on the matter.
"That is why we have asked for an expert legal opinion," she said.
Switzerland's population of eight million people includes an estimated 350,000 Muslims.
Previous similar disputes have centred on Muslim parents who demanded that their daughters be exempt from swimming lessons, a case that led to the parents being fined.
Muslim families have however secured victories in court against schools which sought to ban the full face veil.
