In light of the overall purport of the arguments in the above facts of recognition as to the cause of the claim, it is reasonable to deem that the Defendant prepared and delivered the evidence No. 1 (the tea certificate) to the Plaintiff in the meaning of bearing the obligation jointly, and barring any special circumstance, the Defendant is liable to pay the Plaintiff the principal amount of the loan of this case as 50,000,000,000, and damages for delay.

B. The defendant's defense (i) acknowledged the authenticity of the evidence No. 1 (the second evidence) by the defendant, but argued that it was only formally prepared by the C's request to use the evidence only for the purpose of the joint and several guarantee agreement with the D's spouse, and that it is invalid as a non-author's declaration of intention or a false conspiracy with the other party. However, the disposition document is deemed invalid unless there are special circumstances.
