美国最高法院一致说，对有争议的“美国水域”规则的挑战应由联邦地区而不是上诉审理。decision.

The decision, issued on Jan. 22, adds a layer of uncertainty to the Obama-era rule, which has been stayed by a federal appeals court since 2015, but could now go into effect before the Trump administration has a chance to rescind and replace it, though that is unlikely.

“This decision may lead to some confusion in the coming days and weeks,” the National Association of Home Builders (NAHB) said in a statement. “It’s conceivable that the 2015 rule could take effect in some states unless the courts, Congress or the agencies take action.”

NAHB表示，它将要求北达科他州的联邦地方法院对2015年统治发表全国暂停。其他团体表示，他们将与特朗普政府合作，迅速废除该规则，并用另一项规则代替，这已经在进行中，但这可能至少要花费一年的时间。

The Waters of the U.S (WOTUS) rule was a joint regulation issued by the U.S. Environmental Protection Agency and U.S. Army Corps of Engineers that sought to clarify which wetlands and streams were subject to federal regulatory jurisdiction, an issue that has been unclear following past Supreme Court rulings.

“总的来说，它为EPA和司法部造成了立即的困境，”水资源咨询公司Dawson＆Associates的高级顾问Larry Liebesman说。“如果住宿保持生效，[特朗普政府]将在拟议的撤销和替换方面拥有更多的奢侈。”

该法规的反对者，包括建筑利益和农民，认为这是联邦过度侵犯的一个例子。

In 2015, a U.S. District Court in North Dakota stopped the rule from going into effect in the 13 states that opposed it. The 6th U.S. Circuit Court of Appeals later found that it had jurisdiction and issued a nationwide stay of the rule, which has remained in place.

The National Association of Manufacturers challenged that jurisdiction of the case before the high court, arguing that litigation of the rule belonged in the U.S. district courts.

大厅集团以及全国房屋建筑商协会和美国道路与运输建筑商协会。除其他外，还说应在联邦地方法院一级审理《清洁水法》挑战，更接近法规影响当地项目和土地所有者的地方。18luck官网Arbta在1月22日发布的一份声明中说：“从地方法院开始的诉讼也有更多的上诉可能性，因此有更好的机会做出正确的决定。”

In the Jan. 22 decision, written by Justice Sonia Sotomayor, the high court agreed that the clean water issues belong in district courts.

“法院承认，正如政府所说的那样，将WOTUS统治直接挑战上诉法院可能提高司法效率。但是效率并不是国会的唯一考虑。”索托马约尔写道。“如果国会想优先考虑效率，那么它可以像《清洁空气法》一样对所有国家适用法规进行直接巡回法规的审查。”

NAHB表示，2月，最高法院将向第六巡回法院颁布一项任务，这将导致全国范围内的Wotus逗留。NAHB表示，它将要求北达科他州地方法院将其最初的禁令扩展到反对该法规的13个州的所有50个州。

同时，利伯斯曼（Liebesman）建议那些根据《清洁水法》（Cleat Water Act）受监管的人研究在Wotus裁决之前有效的指导，与监管机构合作，并期望地方法院得到一些指导。
