Although most advice is binding, in comparatively rare instances it is not. For example, many heads of state may choose not to follow advice on a dissolution of parliament where the government has lost the confidence of that body. In some cases, whether the advice is mandatory or truly just advisory depends on the context and authority of the person offering it. Hence the President of Ireland ordinarily is obliged to dissolve Dáil Éireann (the House of Representatives) when advised to do so by the Taoiseach (prime minister). However, where a taoiseach has (in the words of the Irish Constitution) "ceased to retain the support of a majority in Dáil Éireann" (i.e., lost the confidence of parliament) the President has the option of refusing to follow that advice.[2]
^ Some constitutional writers, though not all, capitalise the word to indicate that it refers not merely to an informal suggestion but to a formal constitutional instruction which, in most cases, must be followed.citation needed
