The plenary session of the Supreme Court is to decide on a complex paternity suit against the head of a fertility treatment center by a woman who visited the doctor as a patient and then had a five-year affair with him, during which time she conceived twins following in vitro fertilization. The matter was discussed by a section of the Supreme Court, which referred it to the plenary session, in a decision made public on Saturday. The woman involved – whose name was not made public – is seeking alimony from the doctor, who she claimed had assured her that he would be using their own genetic material during the fertility treatment. However, DNA testing on the twins, who are now 13 years old, showed that this was not the case. Both the mother and the doctor were already married when they met and formed a relationship, and although both obtained divorces they never married each other.
