After Bostanai's death, his sons insisted that the princess and her son were still slaves and hence, their property. The judges were divided in opinion, but finally decided that the legitimate sons of the exilarch should grant letters of manumission to the princess and her son in order to testify to their emancipation. This decision was based on the ground that Bostanai had probably lived in legitimate marriage with this woman, and, although there were no proofs, had presumably first emancipated and then married her.
