You can do this with a calculation/formula.
The exact variable names and value comparisons are going to depend on how you set up all your fields, but it would be something like this:
=IF(Cancel_Radio="Return to Courts","Yes","No")
Where you replace Cancel_Radio with the variable name for your radio (you can select it from the > menu in the advanced tab of the field editor in the calculation section).
Just note that if you checked the "Assign values to choices" option in your radio field, then you need to use those values, not the display text.
