Invalid employment contract creates obligations upon employee acceptance and employer acceptance of work terms.

The Supreme Court dismissed the bankruptcy administrator's claim to establish an invalid employment contract as void ab initio. The court found that the employee was admitted to work, the company treated him as an employee, and the supervisory board modified the contract terms, indicating mutual intent to create a valid relationship. Consequently, the court ruled that obligations arise from the employee's acceptance of work under the contract's conditions, even if the initial written form was defective.
