Re: [poe] What does it mean for permissions/prohibitions/duties if their constraint(s) are (un)satisfied?

> Is it because of the word "effective"?

Yes, see e.g. ->

[effective (ɪˈfɛk tɪv) adj.](http://www.thefreedictionary.com/effective)
> 1. adequate to accomplish a purpose; producing the intended or expected result: effective teaching methods.
> 2. **in operation or in force; functioning; operative: The law becomes effective at midnight.**
> 3. producing a deep or vivid impression; striking: an effective photograph.
> 4. prepared and available for service, esp. military service. 

> Would it be better to state "If all constraints of a Duty are satisfied, then the Duty is considered to be fulfilled".

Yes. 
1. A duty is in effect as long as its associated permission is "valid" (i.e., the permission's constraints are satisfied).
2. A duty is considered to be fulfilled if its constraints are satisfied.
3. For a permission to become effective, it must be valid and all of the permission's duties must be fulfilled.
