Why was Gabriel allowed to stay in the community?

Gabriel is allowed to stay for a second year of nurturing because Jonas's father makes a special request for it.  
At the end of the first year, Gabriel isn't quite sleeping through the night, and he is still a bit underweight.  Readers are told that normally this would cause the child to be labeled "Inadequate" and be grounds for release of the child, but Jonas's father made a special plea before the committee on Gabriel's behalf.  The committee decided to give Gabriel a second year at the nurturing center. In hopes of speeding up his development, Gabriel comes home with Jonas's father for the nights.  The entire family had to sign a pledge that they would not grow emotionally attached to Gabriel and give him up the moment it was requested by the committee.
