I don't. Canon Law is definitely not my thing.  I am relying upon this blurb taken from the article cited:

"Prior to 1917, canon law forbid the closures of churches, and then it was only allowed if the church building was completely destroyed — not even that it was too expensive to repair, but it had to be utterly destroyed. In 1983, Pope John Paul II promulgated a change to the Code of Canon Law that was called for by Pope John XXIII on the same day he called the Second Vatican Council.
These changes incorporated a change to a doctrinal-theological structure that more reflected the spirit of Vatican II as opposed to the Pio-Benedictine code of 1917 that focused more on the norms and procedures.
"For the past 36 years, there has been a massive uptick in closures," Hale said. One change to the 1983 Code of Canon Law is that the process to close a church for grave reasons other than its destruction was established. Hale said this process is "grossly abused."

I just realized that the quote here says that “prior to 1917”. The New Code of Canon Law, under Saint Pius X, was codified in 1917. All canon law before that date was abrogated except, of course, laws that are based on  Divine Law which are reflected in the New Code.

Confederate Catholic

Thanks for the reminder.  Now that I think of it...about 20 years ago when I was stationed in Va Beach, local Catholics pitched in and bought 4 acres of land on Damn Neck Rd for a little under $300k.  It came with a house on the property...not pretty, but had potential for a small conversion to a chapel.  

Long story short, about ten years before that “Father” Williamson helped to found St Benedict’s in Chesapeake.  When the Archibishop Consecrated without Papal Mandate these Traditionalists threw Fr Williamson out and gave their property to the Bishop Sullivan with a promise to provide Traditional Masses...St Benedict’s is now run by FSSP.

Back to the 90’s...because they were previously burned by Traditional Catholics in the area, Fr. Scott demanded that ownership of the land be signed over to the SSPX so that they could be sure that they would not be betrayed again.  Over time the locals were out voted by the SSPX, to their disappointment, and the small house was demolished to build a “real chapel worthy of Our Lord”.  Two or three years after the demolition the SSPX saw a boom in local real estate.  The property was appraised at more than triple it’s original purchase price.  You guessed it...the SSPX decided it would be better to sell the four acres and use the incredible profit to purchase a small existing church....

That was in 2003, last I checked, Immaculate Heart of Mary Mission, still meets at the local hotel for Sunday Mass. I’m not sure whatever happened to the property on Damn Neck Rd but it is obvious that a Church was never built.

I totally forgot how opportunistic the SSPX can be.  Thanks for refreshing my memory, unfortunately.

Phoenix for example (the older church) took years too complete because the district took half of the money earmarked for construction. The priest who completed it took a donation put it in a new account and finished the project.

How "immediately"?
