Abstract
Having explicated "refraining," "omitting," "failing" and "letting happen," it is argued that these cases are not actions but decisions, Having consequences for which one may be blamed or praised. To blame or praise properly we need a clear concept of responsibility. Extending h l a hart's "role-Responsibility," it is suggested that there are "official, Causal" and "casual" role-Responsibilities. The first two involve some people's rights--The last does not--And not discharging them is more serious
