German company law (Gesellschaftsrecht) is an influential legal regime for companies in Germany. The primary form of company is the public company or Aktiengesellschaft (AG). The private company with limited liability is known as a Gesellschaft mit beschränkter Haftung (GmbH). A partnership is called a Kommanditgesellschaft (KG).In Germany, through most of the 19th century the Kommanditgesellschaft (société en commandite in France) was the typical form of business organisation. A "KG" had at least one member with unlimited liability, but other investors' liability was limited to their contribution. A special concession was not required for setting up this company. The first German public company statute was the Prussian Act of 1843. In 1861 the Allgemeines Deutsches Handelsgesetzbuch or the General Commercial Code for all of Germany, as well as Austria, was enacted, which devoted a section to joint stock companies. This allowed incorporation with limited liability. Companies would be constituted with a single board of directors, though they had the option of a two-tiered board system, involving shareholders appointing a supervisory board, which could in turn elect the management board.There were updates to the Allgemeines Deutsches Handelsgesetzbuch in the Aktiennovelle von 1870 (New Company Act 1870) and again in 1884. The 1884 reform mandated that companies have a two-tier board, with the justification that free registration rather than a system of state concession meant a supervisory board was needed to take over the state's monitoring role. The members of the supervisory board were not allowed to serve on the management board. However, shareholders could still directly elect management board members if they so wished. Further reforms led to the Handelsgesetzbuch of 1897, but without changing the basic structure.Shareholders have a list of specific rights allocated to them by the Aktiengesetz, although this is circumscribed by the general principle in AktG §119(2) that issues concerning ‘business leadership’ can only be determined by the executive directors. The voting rights of shareholders are heavily influenced by the banks. Banks appropriate the votes of people who must deposit their share certificates in banks’ accounts. The notable rights for shareholders are as followsThere is no right to control political donations (cf AktG §58).German directors have similar duties to most jurisdictions, primarily a duty of loyalty, and a duty to exercise competent judgment. First, the duty of loyalty, or Treuepflicht, derives from the good faith provision in the civil code (BGB §242).Second, there is a particular prohibition on taking corporate opportunities and a duty of secrecy, AktG §93(1).Third, there is a specific prohibition on competing with the company, AktG §88.Fourth, recently introduced was a ‘business judgment rule’. A new provision, AktG §93(1) says, ‘executive members have to exercise the care of an ordinary and conscientious business leader’.While German corporate theory posits that the supervisory board should do the work of protecting minority shareholders, and is expected to do the litigating against the executive (AktG §111), minority shareholders may also bring claims against directors. Under AktG §147, ten per cent of shareholders, or those with over €1,000,000 may bring a claim against a director for breach of duty. They will have a special representative appointed to carry out the litigation and the company will pay the costs. There is also a procedure for one per cent of shareholders, or those with an interest over €100,000 to bring a claim (AktG §148). Here the court is more stringent, and like the derivative claim in the UK can strike out an application if it finds reasons for it are lacking. There have been cases where the courts have held that majority shareholders owe a duty of good faith to minority shareholders, but also that minorities who can block actions by the company owe duties to the majority.Analogous to the UK Corporate Governance Code, which is also a ‘comply or explain’ law, is the Deutsche Corporate Governance Kodex (AktG §161). It replicates a lot of rules already found in the Aktiengesetz.Under the Mitbestimmungsgesetz, in companies with over 2000 workers just under half the seats on a supervisory board are selected by the workers. In companies with over 500 staff one third of the supervisory must be composed of employee directors under the Drittelbeteiligungsgesetz. With under 500 staff, there is no automatic right of employees to board representation. However, any workplace with over five people allow workers various rights through elected works councils, and if the business has over 20 staff, employees may force the management into arbitration over redundancies.A large German company is required to have a two tier board system. The basic difference to the law, for instance, in the UK, Sweden or the US, is that an executive directors cannot be removed directly by the members of the company (i.e. shareholders typically, and sometimes employees) but only by a second tier "supervisory" board. The Aktiengesetz §76 the executive's primary role is to manage the company, or look after its day-to-day affairs. By contrast under Aktiengesetz §111 the supervisory board's role is stated to be to "supervise" (überwachen). Originally a supervisory board was a default requirement, so companies could choose whether to have one or not. The practice became utilised in most companies by the 1920s, however in the Aktiengesetz 1937, German law made it a requirement to have a supervisory board. This remained in the post-war reforms.Members of the executive ("Vorstand", often translated as ‘management board’) are generally appointed for five years. They can be removed by the supervisory board, but only for a "good reason" (AktG §84(3) ein wichtiger Grund). This includes a vote of no confidence by the shareholders. However, the supervisory board is not bound to act upon a shareholder vote. Within the executive although all members will generally be appointed by the supervisory board, in companies with over 2000 people there must be one ‘staff director’, Arbeitsdirektor, on the executive who is intended to hold the confidence of the employees, under Mitbestimmungsgesetz 1976 §33. Typically this will mean that staff director is nominated by the unions, though no formal procedure is prescribed.In companies with over 2000 employees, the supervisory board ("Aufsichtsrat") is composed of half shareholder appointees (Aktiengesetz §§102 and 119) who can only remove the supervisory board members on a 75% vote (AktG §§102-103). The other half is elected by the employees, though in companies with over 8000 employees the employees can let the unions vote on their behalf (Mitbestimmungsgesetz §§7 and 9). However, one chairperson with the casting vote invariably is chosen by shareholders. Initially both the shareholder and employee sides are meant to reach a consensus on the chair. If they cannot reach consensus, it will go to arbitration, and if a solution is still not reached, the shareholders get to choose (Mitbestimmungsgesetz §27).
