section 284

Directors attendance is required to be noted, however all the directors signature is not required on minutes of the meeting. The Chairman of the meeting can sign the minutes.

Your question is not clear whether that directors father is appointed by the Board or by the shareholders and whether your company is a private limited or a limited company.

It seems there is no compliance with section 284 (i.e. no notice has been served) for removal of director, hence the removal is invalid.

Whether the reduction your shareholding is by increasing their holding of shares or in any other way is not clear. In case the enhancement of their holding, it is to be done according to the Companies Act, 1956, AOA and shareholders agreement if any.

Since your holding is less than 10% you may not represent minority powers. However, you may give a complaint to ROC and RD. There are several other remidies as well, i.e.  filing civil suits, criminal cases etc. Meet any good corporate lawyer and a criminal lawyer.

Write to the ICAI for the mischievous acts of your auditor.
