The Supreme Court is set to rule on June 21 whether a transgender woman can be recognized as a parent of a child she had with a female partner using sperm frozen before her transition.

At the court's Second Petty Bench, Presiding Justice Akira Ojima held a hearing on the case Friday, with the transgender woman in her 40s and her second daughter presenting opinions.

The hearing was a procedure necessary to change the conclusion of the previous ruling by Tokyo High Court, meaning that the high court decision that denied a parent-child relationship between them may be changed.
