this automatic procedure the hospital must give notice of its intention to increase rates. Like the Secretary, we find no unconstitutional imposition by such a purely formal requirement.
The second objection is that the regulations, as originally drafted, provided that rate adjustments put into effect immediately under the regulations were by other terms of the regulations “[sjubject to refund or reduction or both if the hospital fails to meet the criteria and standards necessary for a rate change.”10 If we look at the Act as a whole, it would seem reasonable to conclude that this provision for “refund or reduction” was not intended to apply to adjustments made in connection with Medicare or Medicaid charges. And that this is so was made plain in the final revision of the relevant regulation, § 4.01.-01(d):
Plaintiffs would also find that the provision in § 5.02(b) for “pass-through” of Medicaid and Medicare rate increases is discretionary with the board as evidenced by the use of the word “may.” While the term “may” in a statute or agency regulation dealing with agency power is generally construed as permissive rather than mandatory, the construction of such term — whether discretionary or mandatory — is reached in every case “on the context of the statute [or regulation], and on whether it is fairly to be presumed that it was the intention of the legislature [or agency] to confer a discretionary power or to impose an imperative duty.”

Sutherland Statutory Construction, § 25.03, at 299 (4th 1972), that in determining the proper interpretation in a statute of the words “may” and “shall” it is the intention of the legislature or the proper regulatory agency, which “should be controlling” and that “no formalistic rule of grammar or word form should stand in the way of carrying out [this] legislative intent.” Thus, in a proper case “shall” may properly be construed as permissive,

There can be no question that the board intended the challenged provision in this regulation, even though stated in terms of “may,” to be mandatory. The
