In modern days, a bylaw is a rule governing the internal management of an organization, such as a business corporation. Bylaws cannot countermand governmental law.

In a business situation, bylaws are drafted by a corporation's founders or directors under the authority of its Charter or Articles of Incorporation. Bylaws widely vary from organization to organization, but generally cover topics such as how directors are elected, how meetings of directors (and in the case of a business, shareholders) are conducted, and what officers the organization will have and a description of their duties.

Per a US govt glossary. Does this fit the context?

From Multitran:
подзаконные нормативные акты delegated legislation
подзаконный акт administrative ordinance
подзаконный акт piece of delegated legislation or of subordinate legislation
подзаконный нормоустановительный акт administrative ordinance
подзаконный нормоустановительный акт executive order
подзаконный нормоустановительный акт piece of delegated legislation or of subordinate legislation

out of which "adminstrative ordinance" looks the most credible, I think.

Subordinate legislation is a collective term for statutory rules, regulations, ordinances, by-laws and rules. It is made by persons or bodies to whom Parliament has delegated some of its law-making powers (often a government department). The authority to make subordinate legislation is conferred by an Act of Parliament, known as an enabling or delegating Act. Many principal Acts are also enabling acts. The enabling Act may, and often does, stipulate requirements about the way the subordinate legislation is to be made. Acts are usually general in nature, establishing broad principles. Subordinate legislation will contain the many details necessary to ensure that the Act will operate successfully. Finding and updating subordinate legislation is a very similar process to finding and updating Acts.

Secondary legislation
Secondary legislation include regulations, directives, decisions, recommendations and opinions.

Secondary legislation also includes interinstitutional agreements, which are agreements made between European Union institutions clarifying their respective powers, especially in budgetary matters. The Parliament, Commission and Council are capable of entering into such agreements.

The classification of legislative acts varies among the First, Second and Third Pillars.

Акт подзаконный Law-based act, Ordinance

To beging with, I would not translate Russian "акт" as "act" in English.
Also, I have found this defition very helpful:

подзаконный акт

Concept definition: *An order or regulation issued by the president or some administrative authority under his direction for the purpose of interpreting, implementing or giving administrative effect to a provision of the constitution or of some law or treaty
