The result of the deliberation of the commissioners was a decision in
July, 1647, in favor of Connecticut. This was far from satisfying
Massachusetts, and she reopened the question in September, 1648. To
enforce her arguments, she offered certain amendments to the
confederation, which, if adopted, would have shorn the commissioners
of pretty nearly all their authority. But the commissioners stood
firm, and declared that "they found not sufficient cause to reverse
what was done last year."[11]

Feeling on both sides had now become quite embittered. At a special
meeting of the federal commissioners in July, 1649, Massachusetts
renewed her objections, and during the discussions her commissioners
produced an order,[12] passed two months before by their general
court, which, reciting the decision against Springfield, laid a tax
upon all articles imported to Boston from any one of the other three
confederate colonies, or exported to them from "any part of the Bay."
This proceeding was justly interpreted by the federal commissioners to
mean not only a retaliation upon Connecticut for the Saybrook tax, but
a punishment upon the other two colonies--Plymouth and New Haven--for
taking her side in the court of the confederation.

The commissioners acted with dignified firmness, and forwarded to
Massachusetts a remonstrance in which they pointedly desired "to be
spared in all further agitations concerning Springfield."[13]
Massachusetts reluctantly yielded and the next year repealed her
impost,[14] while Connecticut continued to tax the trade of
Springfield till the ten years expired. Whether the tax imposed by
Connecticut was right or not, Massachusetts had, nevertheless, gone
dangerously near to nullification in these proceedings.
