The Well-being of Future Generations (Wales) Act 2015 is a landmark piece of sustainable development legislation and marks a significant development in the emerging legal identity of Wales. Despite the Act's significance and ambition, it has been criticized as merely ‘aspirational’ – as ‘non-law-bearing’ and unenforceable by legal means. The Act is not without difficulties. However, it also has notable legal and other qualities that are often not captured within the standard justiciability-enforceability frame of analysis. Our aim here is to broaden the context for examining the Act and other ‘aspirational’ legislation like it. To that end, we identify three sets of questions that help to bring out different ideas around the Act's varied enforceability, its possible constitutional status, and its potential role as a bearer of hope.

2015 年《后代福祉（威尔士）法案》是一项具有里程碑意义的可持续发展立法，标志着威尔士新兴法律身份的重大发展。尽管该法案具有重要意义和雄心壮志，但它被批评为仅仅是“雄心勃勃的”——“不具有法律意义”，无法通过法律手段执行。该法案并非没有困难。然而，它也具有显着的法律和其他品质，而这些品质往往无法在标准的可诉性-可执行性分析框架中捕捉到。我们在这里的目的是拓宽审查该法案和其他类似“理想”立法的背景。为此，我们确定了三组问题，这些问题有助于围绕该法案的各种可执行性、可能的宪法地位及其作为希望承载者的潜在作用提出不同的想法。
