Cgroup files and directories can be owned by non-root users, enabling delegation of cgroup administration. In general, the kernel enforces the hierarchical constraints on limits, so that for instance if devices cgroup <filename>/child1</filename> cannot access a disk drive, then <filename>/child1/child2</filename> cannot give itself those rights.
