الاستدلال بعدم العلة على عدم الحكم
To argue that a ruling is absent because its cause is absent.
For example, someone may say that a ruling does not apply because the reason ordinarily cited for it is missing. The crucial question is whether this is the only legally recognized cause of that ruling.
If more than one cause can establish the ruling, absence of one cause does not eliminate every possible basis. Treating the failure of a particular cause as proof of universal absence is a logical and jurisprudential error.
