Before asking question first give details of your question. 

If you want to know whether on the basis of GPA given by your brother you can sell his property or not then the answer is yes.

However in such cases the GPA needs to be registered. 

Dear sir,

If your brother in law is the owner of the property and he has given GPA to other person and if that GPA is registered then ofcourse yes he can sell the property through GPA holder; if GPA is not registered only notarized in such a case there is no valid right to sell the property through GPA holder.

However if your the owner then you too have a right to register GPA in favour of other person to act on your behalf!!

Brother in law can sell property though a power of attorney(POA) holder; and in that case the POA holder will perform the formalities with respect to the sale deed execution on behalf of your brother in law.  in any case, the title of the property can only be passed under a sale deed

A power agent cannot appoint another power agent on behalf of his principal for carrying out the assigned task. 

Your brother in law can POA deed to the other person directly. 

If you have been appointed as his lawful attorney,  you can either rescind it or you may have to do it yourself. 

If a GPA is registered and duly stamped, the GPA holder has the power to execute the sale deed. 

yes you can register in other person favour . 

Please write in detail so that it can be answered properly.

1. GPA and POA are two name of one instrument.
