未定履行期限合同债务的迟延

Delay in Contractual Debt with Undetermined Performance Period

未定履行期限合同债务迟延构成的核心在于确定履行期限。逻辑上,就未定履行期限的合同债务,先确定履行期限才能进一步判断是否构成迟延。确定履行期限时,依照协议补充、合同的补充解释、任意规定之顺序逐步进行。适用任意规定时,若有特别规定,特别规定优先;但特别规定存在不足时,应当结合一般规定进行目的解释和体系解释以补充。《合同法》第62条第4项属于一般任意规定,目的在于确定履行期限,必要的准备时间即为履行期,履行期届满,即陷于迟延,不必另行催告。

The core for the delay in contractual debt with undetermined performance period is to determine the deadline for performance. Logically, it is necessary to determine the deadline for performance in order to further determine whether it is delay in performance. When determining the deadline for performance, it shall be carried out in accordance with the supplement of the agreement, the supplementary explanation of the contract, and the order of optionalprovisions. Whenoptional regulations are applied, if there are special provisions, special provisions shall be given priority, but if there are deficiencies in special provisions, the purpose explanation and system explanation shall be supplemented in accordance with the general provisions.The Article 62, Clause 4 of Contract Law is a general optional provision, whose purpose is to determine the deadline of performance. The necessary time for preparation is the deadline for performance, when the performance period is expired, it will be delayed, and there is no need for interpellation.
