Labour law: Dismissal - current LAG ruling strengthens protection against dismissal
In its judgement of 4 May 2023 (case no. 6 Sa 684/22), the Cologne Higher Labour Court significantly strengthens the protection against dismissal for works council members and election committee members. In the specific case, it declared the dismissal of a photographer to be invalid as there was no independent works department and options for continued employment were not sufficiently examined. Employers and employees in Cologne should therefore seek legal support at an early stage in the event of dismissals in order to minimise legal risks and assert their rights in the best possible way.
Schengen visa denied for business trip - Berlin Administrative Court demands new decision
The ruling of the Berlin Administrative Court of 8 November 2023 (case no. 16 K 594/22 V) clearly shows that business travellers and inviting German companies do not simply have to accept a visa refusal. In the case in question, a Pakistani entrepreneur was refused a Schengen visa due to general security concerns. The court made it clear that although authorities have discretionary powers, they must present concrete and reliable facts in order to assume a threat to public order. As this had not been done, the court obliged the authorities to make a new decision on the visa application. Companies and business travellers are advised to prepare visa applications carefully and to seek legal advice in the event of a rejection.
VG Berlin: Visit visa refused due to lack of intention to return (judgement of 06.03.2024)
In a recent judgement, the Berlin Administrative Court confirmed the rejection of a Schengen visit visa for a Russian citizen. The decisive factor was reasonable doubt about his intention to return due to a lack of economic and family ties. The case makes it clear that visa applicants must provide detailed evidence to demonstrate their willingness to return. Companies and applicants should avoid typical mistakes when applying in order to effectively prevent rejections.
