Correção de texto com palavra "unleashed"

Oi,
gostaria de saber se posso colocar esta frase: Therefore, this arrangement unleashed a problematic externality of restraining the capabilities in governing the cities. Is it a correct form to put down a basic difference in the decision making process between both levels of power?

O contexto é:

Differently from the Parliamentary system, maybe not so evident in this ongoing coalition – form, where the power, especially the one of policy-making had transferred from the cabinet to the Prime-Minister, the local government has been suffering from a disease originated by the separate governing bodies – Council and the executive. Therefore, this arrangement unleashed a problematic externality of restraining the capabilities in governing the cities. Is it a correct form to put down a basic difference in the decision making process between both levels of power?

Obrigada de novo!
