Section 15-5. Consequences of formal errors in connection with notice of dismissal

(1) If the employer's notice is not given in writing or does not include information as referred to in section 15-4 and the employee institutes legal proceedings within 4 months from the date that notice is given, the notice shall be ruled invalid unless special circumstances make this clearly unreasonable.
(2) If the notice is invalid, the employee may claim compensation. The same shall apply if the notice provides inadequate information, but the employee does not demand that it be ruled invalid or it is not ruled invalid because special circumstances make this clearly unreasonable, cf. the first paragraph. Compensation shall be decided in accordance with section 15-12, second paragraph.
