We study a \( \mathbb{Z}G \)-module A such that \( \mathbb{Z} \) is the ring of integer numbers, the group G has an infinite sectional p-rank (or an infinite 0-rank), C G (A) = 1, A is not a minimax \( \mathbb{Z} \)-module, and, for any proper subgroup H of infinite sectional p-rank (or infinite 0-rank, respectively), the quotient module A/C A (H) is a minimax \( \mathbb{Z} \)-module. It is shown that if the group G is locally soluble, then it is soluble. Some properties of soluble groups of this kind are discussed.
