(The idiom comes from British politics. There are two parliamentary houses, and the House of Lords never mentions the House of Commons by name: calling it "another place" (or "the other place"). But it thinks about it a lot.)
A very confusing idiom. Should be discouraged? -- BayleShanks
It's not being abused. It's not even being used.
The analogy is that the power resides at AnotherPlace, while ThisHouse has more of a scrutiny/oversight role... and is increasingly regarded as irrelevant by the executive branch?
