In 1998, the Czech parliament passed a bill that Czech Sign Language was officially recognized as the first language of the Deaf people in Czech Republic.
Deaf people have the right to get 24-hour sign language interpreting service at no charge. Deaf children have the right to get education in their native sign language. In addition, under the law, parents of deaf children have the right to attend sign language classes at no charge. Although, the law didn't include the interpreting in high schools, universities, and courts.Source: https://en.wikipedia.org/wiki/Legal_recognition_of_sign_languages#:~:text=Czech%20Republic,155%2F1998%20Sb").
