Expelled shareholders can appeal against the squeeze out according to § 243 AktG. Also, according to this section, some reasons, such as inadequate compensation, are not sufficient to inhibit the squeeze out. Even while the rescission proceedings are still running the main shareholder has the right to register in the Commercial Registry if he meets the preconditions defined in §§ 327e sec. 2, § 319 Abs. 5, 6 AktG; by doing so an approval process is initiated and all shares held by minor shareholders devolve to him.
