OPINION
Since
Tafel Estate,
In 1923 Henry Biddle died a resident of Chester County. By item SIXTH of his will he left his residuary estate in trust, directing payment of half the income to his daughter Mildred L. Cadwalader for her life, and the other half, per stirpes, to the issue of his deceased daughter, Juliet DaCosta. The testator instructed that on the death of his daughter Mildred the income be paid to his grandchildren, per capita, and to the issue of any deceased grandchildrеn, per stirpes. 1 The will was duly probated on July 9, 1923 and administration of the trust began.
On September 19, 1949 testator’s daughter Mildred died. Shortly thereafter, on February 9, 1950, C. Alexander Da-Costa, one of testator’s three grandchildren also died. He was survived by two natural children, Charles A. DaCosta, Jr. and Peter M. DaCostа, and by appellant, James Murdock DaCosta, whom C. Alexander DaCosta had adopted on April 25, 1942 when appellant was thirteen years old.
After these deaths the trustees presented an accounting of testator’s estate to the Orphans’ Court of Chester County. *620 The proposed distribution divided C. Alexander DaCosta’s one-third income share between his two natural children and excluded appellant. Appellant was notified of the accounting and of the proposed distribution plan but asserted no claim. The accounting was confirmed by decree nisi and then confirmed absolutely by pro forma decree on January 21, 1952. The payment of trust income has continued until this present accounting. 2
As already stated, in 1972 this Court announced the rule that testamentary grants to “children” should be read to include adopted children unless the testator’s intеntion to exclude adopted children clearly appears.

Estate of Sykes,
The orphans’ court refused to еntertain the merits of appellant’s claim. The orphans’ court acknowledged that appellant had never previously presented any claim to participate in this trust and that the court had never previously determined his right to participate. Nevertheless, the orphans’ court, relying principally upon
Tower Estate,
The continuing refusal of a majority of this Court to adopt the res judicata rule is illustrated by
Fownes Estate,
Similarly, res judicata does not bar the claim of the present appellant. Appellant makes no claim to any trust income already distributed, rather he seeks only to participatе in future distributions of income generated by the trust. Most importantly, he seeks to do so on the basis of a rule of law recently announced by this Court. In such circumstances, the appropriate and fair resolution is for the orphans’ court to allow participation in income earned and distributed in the future.
It is well established that “[a] rule of law made in the distribution of a portion of an estate is not binding upon a court in a subsequent adjudication relating to another portion.”
Estate of Flinn,
The application of these principles is appropriate here where the prior audit was based on a legal doctrine no longer followed.
Estate of Flinn,
supra,
Our determination here is no morе than an application of the result reached by this Court just one year ago in
Estate of DeRoy,
More importantly, DeRoy emphasized the unfairness of precluding the adopted child from the benefits of our decision in Tafel. DeRoy quoted with approval the Restatement of Judgments, § 70, Comment f (1948 Supp.) which provides that the determination of a question of law is not conclusive between the parties in a subsequent adjudication “if it would be unjust to one of the parties or to third persons to apply one rule of law in subsequent actions between the same parties and to apply a different rule of law between other persons.” As DeRoy explained
“It would obviously be unjust to apply [the rule of Tafel Estate] to adopted children other thаn appellant while adhering to the former rule when called upon to decide how the principal of the instant trust should be distributed.”
“§ 68.1 Exceptions to the General Rule of Issue Preclusion
Although an issue is actually litigated and determined by a valid and final judgment, and the determination is essential to the judgment, relitigation of the issue in a subsequent action between the parties is not precluded in the following circumstances:
******
(b) The issue is one of law and. .
(ii) a new determination is warranted in order to take аccount of an intervening change in the applicable legal context or otherwise to avoid inequitable administration of the laws . . . .”
*624 The orphans’ court should have been guided by this principle. Our decision in Tafel redressed a denial of rights which had persisted unnecessarily and unfairly for mаny years. Appellant’s claim to future distributions of the trust income must be determined in the light of this important intervening change in the law.
We therefore reach the merits of appellant’s claim. The natural children urge that the presumption that adopted children be included is inapplicable in this case because the language of Henry Biddle’s will demonstrates his intention to exclude adopted children. This argument is completely meritless. Of course, if the language of testator’s will disclosed testator’s intention with reasonable certainty that intention would be controlling.
Estate of Sykes,
The natural children also urge that our decision in
Tafel
is not applicable to the 1923 Biddle will because
Tafel
was based on a construction of the Adoption Act of 1925, Act of April 4, 1925, P.L. 127, § 4, 1 P.S. § 4 (1963). We have previously rejected this argument in
Estate of Flinn,
supra,
*625 The decree of the Court of Common Pleas of Chester County, Orphans’ Court Division, is reversed and this case is remanded for proceedings consistent with this opinion.
Each party pay own costs.
Notes
. The relevant portion of item SIXTH of testatоr’s will provides as follows:
“Upon the death of my said daughter, Mildred L. Cadwalader, to pay and divide the entire income from my said residuary estate during the continuance of this trust among all of my grandchildren, share and share alike, such grandchildren to take per capita and not per stirpes. If, however, during the continuance of the said trust any of such grandchildren shall die, leaving children or issue of deceased children him or her surviving, such children and issue of deceased children to take among them, per stirpes, the share of income which their parent would have takеn if living. If, however, any of such grandchildren shall die during the continuance of the said trust without leaving children or issue of deceased children him or her surviving, then the share of the said grandchild so dying shall be held upon the same terms of trust and with the same remainders over as is herein provided for the share оf my other grandchildren.”
. Trust payments are to end and the trust principal is to be distributed at the death of the last grandchild who was living at the time of Henry Biddle’s death. One such grandchild is now living.
Because of the death of a trustee, another accounting was filed in 1958. Appellant did not receive notiсe of this accounting and all parties agree that the accounting is not relevant to any present issue.
. Because appellant and his step-brothers are both represented by • counsel and because appellant seeks only prospective inclusion, the trustees have, properly, not taken any position on appellant’s claim. See
Trusts of Holdeen,
. We note that there has been litigation concerning separate property originating from the estate of testator’s brother, W. Lyman Biddle. Testator’s brother died in 1920, a resident of Montgomеry County. His will left one-third of his residuary estate in trust, directing that the income be paid to his sister during her lifetime. . On her death, one-half of the remainder of the trust was to go to testator, if living,
*625
and if not, to testator’s issue as he might appoint, and in default of appointment to testator’s issue outright. The sister died in 1937-, and in
Biddle’s Estate,
The record indicates that in 1950 appellant sought to participate as an income beneficiary of this Montgomery County trust. The Orphans’ Court of Montgomery County denied appellant’s claim. Appellant took timely exceptions to that decree, but his exceptions were dismissed and the orphans’ court decree was made final on February 27, 1951. Appellant did not file any appeal.
The record further indicates that appellant has recently sought, based on Tafel, to participate in future income distributions of the Montgomery County property. The orphans’ court there refused to allow appellant to participate on the ground of res judicata. Appellant took timely exceptions to the Montgomery County decree nisi, which were dismissed, and then appealed the Montgomery County decree to this Court. That appeal, however, has been discontinued.
Appellant’s entitlеment to any portion of the Montgomery County property is not before us and we express no view on that claim.
We agree with the Orphans’ Court Division of Chester County, however, that the Montgomery County litigation, as it involves a distinct and separate fund from a separate estate shоuld not preclude the present auditing court from now applying the correct rule of law to future distributions of the Chester County property. Rights to a distinct piece of property are not determined by a judgment concerning another piece of unrelated property.
Estate of Flinn,
