(supra), summed up the position as follows: "Under our jurisprudence the Government is not exempt from liability to carry out the representation made by it as to its future conduct and it cannot on some undefined and undisclosed ground of necessity or expediency fail to carry out the promise solemnly made by it, nor claim to be the Judge of its own obligation to the citizen on an ex parte appraisement of the circumstances in which the obligation has arisen." The law may, therefore, now be taken to be settled as a result of this decision that where the Government makes a promise knowing or intending that it would be acted on by the promises and, in fact, the promisee, acting in reliance on it, alters his position, the Government would be held bound by the promise and the promise would be enforceable against the Government at the instance of the promises, notwithstanding that there is no consideration for the promise and the promise is not recorded in the form of a formal contract 683 as required by Article 299 of the Constitution.
