In effect, the HMC prohibits skipping a governing head position, as in (ii): buy moves to COMP in disregard of its being properly governed only by the I0 will.
(ii) * [CP What [C buyi] [IP John [I will] [VP ti]]]?Recently, it has been argued that the HMC can be derived from more general principles, such as the ECP.
