Questão jurídica principal
Whether the employer had a substantive claim to removal of the unlawful situation under Art. 340b(3) OR despite the absence of a special written agreement.
Decisão extraída
No. Without a special written agreement authorizing removal, federal law excludes a claim to eliminate the contractual breach.
Fundamentação extraída
Art. 340b(3) OR sets a formal prerequisite for such relief. The provision is lex specialis over Art. 160 OR; therefore the general penalty-clause logic cannot bypass the statutory requirement.
