A “landmark” decision:

And here’s an excerpt from the linked-to New York Post article with the bonus suggestion that this might all be for immigration purposes:

The state’s highest court has toppled a cultural taboo — legalizing a degree of incest, at least between an uncle and niece — in a unanimous ruling.

While the laws against “parent-child and brother-sister marriages . . . are grounded in the almost universal horror with which such marriages are viewed . . . there is no comparably strong objection to uncle-niece marriages,” Tuesday’s ruling reads.

Judge Robert Smith of the Court of Appeals wrote that such unions were lawful in New York until 1893 and Rhode Island allows them.

The decision stems from a case brought by Vietnamese citizen Huyen Nguyen, 34, a woman who had appealed a ruling by an immigration judge.

The judge had tried to boot her from the United States after declaring that her 2000 marriage in Rochester to her mother’s half-brother was invalid.

So now Dreamers can come to New York and marry their relatives to stay in the United States? If it’s for true love, of course.
